What is the study of light called?
- A.
Spectroscopy
- B.
Photonics
- C.
Spectrometry
- D.
Optics
Correct Answer
D. OpticsExplanation
Optics is the study of light and its behavior, including its properties, interactions with matter, and the instruments used to detect and manipulate it. It encompasses various branches such as geometric optics, which deals with the propagation of light in straight lines, and physical optics, which focuses on the wave nature of light. Spectroscopy, photonics, and spectrometry are all related fields that utilize the principles of optics in their respective studies, but they do not encompass the entire study of light like optics does.Rate this question:

Which of the following are light-based technologies?
- A.
Microscope
- B.
X-ray machine
- C.
Telescope
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
All of the given options, microscope, X-ray machine, and telescope, are light-based technologies. A microscope uses light to magnify small objects and make them visible to the human eye. An X-ray machine uses X-rays, which are a form of electromagnetic radiation, to create images of the internal structures of the body. A telescope uses lenses or mirrors to gather and focus light from distant objects, allowing us to see them more clearly. Therefore, all of these options involve the use of light in different ways.Rate this question:

Which object breaks up white light to show its different colors?
- A.
Prism
- B.
Telescope
- C.
Lens
- D.
Microscope
Correct Answer
A. PrismExplanation
A prism is an object that breaks up white light to show its different colors. When white light passes through a prism, it gets refracted or bent, causing the different wavelengths of light to separate and form a spectrum of colors. This phenomenon is known as dispersion. Prisms are commonly used in physics and optics experiments to study the properties of light and to create rainbows.Rate this question:

How is the wavelength of light related to its frequency?
- A.
Higher the frequency, the longer the wavelength.
- B.
Higher the frequency, the shorter the wavelength.
- C.
The wavelength is equal to the frequency.
- D.
The wavelength is not related to the frequency.
Correct Answer
B. Higher the frequency, the shorter the wavelength.Explanation
The relationship between the wavelength of light and its frequency is inversely proportional. This means that as the frequency of light increases, the wavelength decreases, and vice versa. This can be explained by the wave equation, where the speed of light is constant. Since the speed of light is fixed, if the frequency increases, the wavelength must decrease to maintain the same speed. Therefore, higher frequency light has shorter wavelengths.Rate this question:
