Supaya kita bisa melihat sebuah benda maka kita memperlukan ....
- A.
Cahaya
- B.
Suara
- C.
Panas
- D.
Gerak
Correct Answer
A. CahayaExplanation
To be able to see an object, we need light. Light is essential for vision as it illuminates objects, allowing our eyes to detect and process the information. Without light, our eyes would not receive any visual stimuli, and therefore we would not be able to see anything.Rate this question:

Benda bening
- B.
Benda gelap
- C.
Benda keruh
- D.
Benda coklat
Correct Answer
A. Benda beningExplanation
A benda bening is a term used to describe an object that is transparent or translucent, allowing light to pass through it. This is in contrast to benda gelap, benda keruh, and benda coklat, which all refer to objects that do not allow light to pass through.Rate this question:

Contoh benda bening adalah sebagai berikut ....
- A.
Kaca bening, air bersih, susu
- B.
Kaca bening, air kotor, kayu
- C.
Kaca bening, es batu, air jernih
- D.
Batu, air jernih, kayu
Correct Answer
C. Kaca bening, es batu, air jernihExplanation
The correct answer is kaca bening, es batu, air jernih. These objects are transparent or clear, allowing light to pass through them without scattering. Kaca bening refers to clear glass, es batu refers to clear ice cubes, and air jernih refers to clear water. This distinguishes them from the other options that include objects that are not transparent or clear, such as air kotor (dirty air), kayu (wood), and batu (stone).Rate this question:

Berikut adalah sifat-sifat yang dimiliki oleh cahaya, kecuali ....
- A.
Dapat dipantulkan
- B.
Dapat dibiaskan
- C.
Merambat lurus
- D.
Merambat berbalik
Correct Answer
D. Merambat berbalikExplanation
The given answer, "merambat berbalik," is not a characteristic of light. Light does not propagate or travel in a backward direction. It always travels in a straight line and can be reflected or refracted, but it does not reverse its direction of propagation.Rate this question:

Berikut ini adalah contoh benda buram yaitu ....
- A.
Kaca
- B.
Kayu
- C.
Kertas
- D.
Air jernih
Correct Answer
C. KertasExplanation
The correct answer is "kertas" because kertas is an example of a benda buram (opaque object) as it does not allow light to pass through it easily. Unlike kaca (glass) or air jernih (clear water), kertas is not transparent and blocks the passage of light, making it a suitable example of a benda buram.Rate this question:

Pada hukum pemantulan cahaya, sudut datang sama dengan ....
- A.
Sudut pantul
- B.
Sudut pergi
- C.
Sudut titik
- D.
Sudut searah
Correct Answer
A. Sudut pantulExplanation
In the law of reflection, the angle of incidence is equal to the angle of reflection. This means that when light rays hit a surface and bounce off, the angle at which they approach the surface is the same as the angle at which they leave the surface. This phenomenon is known as the angle of reflection.Rate this question:

Pemantulan baur terjadi karena sinar mengenai permukaan benda ....
- A.
Halus
- B.
Kasar
- C.
Gelap
- D.
Bening
Correct Answer
B. KasarExplanation
When light hits a rough surface, it scatters in different directions. This scattering of light is known as diffuse reflection. The roughness of the surface causes the light to bounce off in various angles, resulting in a scattered reflection. Therefore, the correct answer is "Kasar" which means rough in English.Rate this question:

Bayangan yang dihasilkan sama dengan bendanya. Pemantulan terjadi pada cermin ....
- A.
Cembung
- B.
Cekung
- C.
Datar
- D.
Ganda
Correct Answer
C. DatarExplanation
The correct answer is "datar". When an object is placed in front of a flat mirror, the reflection produced is an exact replica of the object. This is because a flat mirror reflects light rays in a way that preserves the size and shape of the object being reflected.Rate this question:

Bayangan yang dihasilkan oleh cermin cembung adalah ....
- A.
Semu, tegak, diperkecil
- B.
Semu, terbalik, diperkecil
- C.
Nyata, tegak, diperbesar
- D.
Nyata, terbalik, diperbesar
Correct Answer
A. Semu, tegak, diperkecilExplanation
The correct answer is "semu, tegak, diperkecil". This means that the image produced by a convex mirror is virtual (not real), upright, and diminished in size. Convex mirrors are curved outward and cause light rays to diverge, resulting in a smaller and upright image.Rate this question:

- B.
400.000 km/detik
- C.
300.000 km/detik
- D.
500.000 km/detik
Correct Answer
C. 300.000 km/detikExplanation
The correct answer is 300.000 km/detik. This is the speed of light in a vacuum. According to the theory of relativity, the speed of light is constant and is the fastest speed possible in the universe. It is approximately 300,000 kilometers per second, or about 186,000 miles per second.Rate this question:

Warna-warni di langit yang berasal dari titik-titik air hujan yang terkena sinar matahari disebut ....
- A.
Fatamorgana
- B.
Pelangi
- C.
Hujan
- D.
Petir
Correct Answer
B. PelangiExplanation
A rainbow is formed when sunlight passes through raindrops in the air. The sunlight is refracted, or bent, as it enters the raindrop, then it reflects off the inside surface of the drop and finally refracts again as it leaves the drop. This bending and reflecting of light causes the different colors in the sunlight to spread out and form a circle of colors in the sky, known as a rainbow. Therefore, the correct answer is Pelangi, which means rainbow in Indonesian.Rate this question:

Correct Answer
B. Benda-benda yang ukurannya sangat kecilExplanation
Mikroskop digunakan untuk melihat benda-benda yang ukurannya sangat kecil. Mikroskop memungkinkan kita untuk melihat detail dan struktur benda-benda yang tidak dapat dilihat dengan mata telanjang. Dengan menggunakan mikroskop, kita dapat memperbesar gambar benda-benda kecil seperti sel, bakteri, atau partikel-partikel kecil lainnya sehingga dapat diamati dengan lebih jelas dan mendetail.Rate this question:

Pemantulan cahaya yang terjadi pada permukaan yang rata adalah pemantulan ....
- A.
Teratur
- B.
Searah
- C.
Tidak teratur
- D.
Tidak terarah
Correct Answer
A. TeraturExplanation
The correct answer is "teratur" because when light reflects off a smooth surface, such as a mirror or still water, the reflected rays of light bounce off at the same angle as the incident rays. This is known as regular or specular reflection, where the reflected light is organized and follows a specific pattern.Rate this question:

Lensa cembung atau konveks bersifat mengumpulkan sinar. Sedangkan lensa cekung atau konkaf bersifat ....
- A.
Menyebarkan sinar.
- B.
Membelokkan sinar
- C.
Membiaskan sinar
- D.
Menyatukan sinar
Correct Answer
A. Menyebarkan sinar.Explanation
Lensa cembung atau konveks memiliki bentuk yang menumpuk dan mampu mengumpulkan sinar, sehingga dapat membentuk gambar yang lebih fokus. Di sisi lain, lensa cekung atau konkaf memiliki bentuk yang menyebar dan mampu menyebarkan sinar, sehingga tidak dapat mengumpulkan sinar dengan baik. Oleh karena itu, jawaban yang tepat adalah "menyebarkan sinar".Rate this question:

Alat untuk melihat menjadi lebih besar adalah ....
- A.
Cermin
- B.
Lup
- C.
Spion
- D.
Periskop
Correct Answer
B. LupExplanation
The correct answer is "Lup." A "lup" is a magnifying glass or a lens that is used to make objects appear larger or closer. It is commonly used in various fields such as science, medicine, and reading to examine small details or to enhance visibility. A mirror (cermin), a mirror-like object used in vehicles (spion), and a periscope are not specifically designed for magnification purposes.Rate this question:

Lensa yang dekat ke mata pada mikroskop disebut ....
- A.
Lensa obyektif
- B.
Lensa pembalik
- C.
Lensa okuler
- D.
lensa cembung
Correct Answer
C. Lensa okulerExplanation
The lens that is closest to the eye in a microscope is called the eyepiece or ocular lens. It is responsible for magnifying the image produced by the objective lens and allowing the viewer to see the magnified image. The objective lens, on the other hand, is the lens closest to the object being viewed and is responsible for gathering light and forming the initial image. Therefore, the correct answer is "lensa okuler" which translates to "eyepiece lens" in English.Rate this question:
