FAQs on Sound Class 8 Worksheet Science Chapter 11
| 1. What is sound and how is it produced? |  |
Ans. Sound is a form of energy that is created by vibrations. It is produced when an object vibrates and creates waves of pressure that travel through a medium, such as air, water, or solids. These waves then reach our ears and are detected as sound.
| 2. How does sound travel through different mediums? | |
Ans. Sound travels through different mediums by vibrating the particles of the medium. In solids, sound travels fastest because the particles are closely packed together. In liquids, sound travels slower because the particles are more spread out. In gases, such as air, sound travels even slower due to the larger gaps between particles.
| 3. What is the speed of sound and does it vary in different mediums? | |
Ans. The speed of sound is the rate at which sound waves travel through a medium. In dry air at room temperature, sound travels at approximately 343 meters per second (or about 1,235 kilometers per hour). However, the speed of sound can vary in different mediums. For example, sound travels faster in solids than in liquids or gases due to the density and arrangement of particles.
| 4. How does the pitch of a sound relate to its frequency? | |
Ans. The pitch of a sound refers to how high or low it sounds. It is determined by the frequency of the sound waves. Higher frequency sound waves have a higher pitch, while lower frequency sound waves have a lower pitch. For example, a high-pitched sound, like a whistle, has a higher frequency than a low-pitched sound, like a bass drum.
| 5. How does sound intensity affect our perception of loudness? | |
Ans. Sound intensity refers to the amount of energy carried by sound waves and is related to the perceived loudness of a sound. The greater the sound intensity, the louder the sound. Our ears are sensitive to changes in sound intensity and can perceive a wide range of loudness levels. However, prolonged exposure to high-intensity sounds can lead to hearing damage.
