Sample questions

1. Which of the following best describes sound?

   1. A form of light energy
   2. A vibration that travels through a medium
   3. A type of heat transfer
   4. A magnetic field
   Show answer

   Answer: B. A vibration that travels through a medium

   Sound is produced by vibrations, and these vibrations need a medium (like air, water, or solids) to travel from the source to the listener's ear. Light is a different form of energy, and heat transfer involves the movement of thermal energy.

2. Which of the following is an example of sound being absorbed rather than reflected?

   1. Sound echoing in an empty hall
   2. Sound bouncing off a hard wall
   3. Sound being muffled by curtains
   4. Sound from a bell in a closed room
   Show answer

   Answer: C. Sound being muffled by curtains

   Soft, porous materials like curtains are good at absorbing sound energy, reducing echoes and reflections. Hard surfaces, on the other hand, tend to reflect sound waves.

3. Which of the following is NOT a characteristic of noise?

   1. Unpleasant to hear
   2. Irregular vibrations
   3. Consistent pitch
   4. Loudness
   Show answer

   Answer: C. Consistent pitch

   Noise is typically characterized by irregular vibrations and a lack of consistent pitch, making it unpleasant to hear and often loud. Musical sounds, in contrast, usually have regular vibrations and a consistent pitch.

4. When you shout at a cliff and hear your voice come back after a few seconds, what is that phenomenon called?

   1. Absorption
   2. Refraction
   3. Echo
   4. Diffraction
   Show answer

   Answer: C. Echo

   An echo is the reflection of sound waves that arrives at the listener with a delay after the direct sound. This happens when sound waves bounce off a hard surface like a cliff.

5. If you strike a tuning fork and then touch it to the surface of water, what do you observe?

   1. The water evaporates quickly.
   2. The water ripples or splashes.
   3. The water becomes still.
   4. The water turns into ice.
   Show answer

   Answer: B. The water ripples or splashes.

   The tuning fork vibrates with a significant amplitude when struck. When it touches the water, these vibrations are transferred to the water, causing it to ripple or splash.
