FAQs on Sound Overview Video Lecture - Science Class 8
| 1. What is sound? |  |
Ans. Sound is a form of energy that is transmitted through vibrations in a medium such as air, water, or solids. It is produced when an object vibrates, creating changes in air pressure that our ears can detect.
| 2. How does sound travel through different mediums? | |
Ans. Sound travels through different mediums by causing particles in the medium to vibrate. In solids, the particles are tightly packed and transmit sound quickly, while in liquids and gases, the particles are more spread out, causing sound to travel slower.
| 3. What is the speed of sound in air? | |
Ans. The speed of sound in air is approximately 343 meters per second at room temperature. This speed can vary depending on factors such as temperature, humidity, and altitude.
| 4. How is sound measured? | |
Ans. Sound is measured in decibels (dB), which is a unit that quantifies the intensity or loudness of sound. The decibel scale is logarithmic, meaning that each increase of 10 dB represents a tenfold increase in sound intensity.
| 5. Can sound waves travel through a vacuum? | |
Ans. No, sound waves cannot travel through a vacuum because they require a medium to propagate. In the absence of a medium, such as in outer space, sound waves are unable to travel.
