Sound energy test: a trivia quiz. Sound is a type of mechanical energy and needs a medium for it to move from one place to another through vibrations. Sound energy comes in handy when it comes to learning about our surroundings. By taking this quiz, you stand a chance at learning more about sound energy, how it travels as well some of the factors affecting how it is received. Do give it a shot!
- 1.
Which among the following statements is TRUE about sound?
- A.
The harder you tap an object, the lesser it will vibrate.
- B.
The more an object vibrates, the louder is the sound.
- C.
The loudness of the sound depends on the weight of the vibrating object.
- D.
The size of the object does not affect the loudness or softness of sound.
Correct Answer
B. The more an object vibrates, the louder is the sound. -
- 2.
Which among the following is TRUE about frequency?
- A.
Slow vibrations create a high note.
- B.
Faster vibrations give low frequency.
- C.
Faster vibrations give high frequency.
- D.
Both a and b
Correct Answer
C. Faster vibrations give high frequency.Explanation
Faster vibrations give high frequency because frequency is defined as the number of vibrations or cycles per unit of time. When vibrations occur more quickly, there are more cycles happening in a given amount of time, resulting in a higher frequency.Rate this question:

Which among the following vibrations do humans can hear?
- A.
22 000 vibrations per second
- B.
22 vibrations per second
- C.
18 vibrations per second
- D.
180 000 vibrations per second
Correct Answer
B. 22 vibrations per secondExplanation
Humans can hear vibrations within a specific range called the audible frequency range. This range typically falls between 20 and 20,000 vibrations per second, or hertz (Hz). The answer "22 vibrations per second" falls within this audible frequency range and is therefore the correct answer.Rate this question:

Why do we usually see a flash of lightning before we hear thunder?
- A.
Like light, sound travels at different speeds.
- B.
Sound waves travels faster through a warmer medium.
- C.
Sound travels faster than light.
- D.
Sound travels faster through solids.
Correct Answer
C. Sound travels faster than light.Explanation
The given answer is incorrect. In reality, light travels much faster than sound. The reason we usually see a flash of lightning before hearing thunder is because light travels faster than sound. Light waves travel at a speed of approximately 299,792 kilometers per second, while sound waves travel at a speed of around 343 meters per second. Therefore, the light from the lightning reaches our eyes almost instantly, while the sound takes longer to reach our ears, resulting in the delay between seeing the flash and hearing the thunder.Rate this question:

How can you reduce the echoes in your room?
- A.
Keep the room bigger.
- B.
Use smooth wall materials.
- C.
Keep the room smaller.
- D.
Use curtains and rugs.
Correct Answer
D. Use curtains and rugs.Explanation
Using curtains and rugs can help reduce echoes in a room because they absorb sound waves and prevent them from bouncing off hard surfaces. Curtains can be hung on walls or windows to absorb sound, while rugs can be placed on the floor to absorb sound vibrations. By reducing the amount of sound reflection, curtains and rugs create a more acoustically balanced environment, reducing echoes and improving the overall sound quality in the room.Rate this question:

How can one minimize noise?
- A.
Speak in a loud voice.
- B.
Shout into another person's ear.
- C.
Avoid making unnecessary noise.
- D.
Tune the TV and radio set to full volume.
Correct Answer
C. Avoid making unnecessary noise.Explanation
To minimize noise, it is important to avoid making unnecessary noise. This means refraining from activities that create loud or disruptive sounds, such as banging objects, playing loud music, or engaging in noisy conversations. By being mindful of one's actions and surroundings, and making an effort to keep noise levels low, a quieter and more peaceful environment can be achieved.Rate this question:

Check the properties of sound.
- A.
Sound travels through air only.
- B.
Sound can be absorbed.
- C.
Sound can be reflected.
- D.
Sound travels through air, water, and solids.
- E.
The loudness of sounds can be modified but the pitch cannot.
- F.
The pitch and loudness can be modified.
Correct Answer(s)
B. Sound can be absorbed.
C. Sound can be reflected.
D. Sound travels through air, water, and solids.
F. The pitch and loudness can be modified.Explanation
The correct answer is that sound can be absorbed, sound can be reflected, sound travels through air, water, and solids, and the pitch and loudness can be modified. This is because sound waves can be absorbed by certain materials, such as foam or fabric, causing the sound to decrease in intensity. Sound waves can also be reflected off surfaces, like walls or mirrors, causing an echo or reverberation. Additionally, sound waves can travel through different mediums, including air, water, and solids. Lastly, the pitch and loudness of sound can be altered by changing the frequency and amplitude of the sound waves respectively.Rate this question:
