Answers
Answer:
1. Answer: Explanation: Sound is the sensation produced in ears by vibrations in a body which makes us able to hear. Experiment: Vibration caused in a tuning fork makes sound and if it is dipped in water, we can see waves which proves that vibrations produce sound.
2. a) 1)If the wavelength of sound is high then it can reach to long distances. 2)In solid medium sound travels faster than in air.
b) For a sound wave traveling through air, the vibrations of the particles are best described as longitudinal. ... Sound waves in air (and any fluid medium) are longitudinal waves because particles of the medium through which the sound is transported vibrate parallel to the direction that the sound wave moves.
3. When a sound passes through a medium it sends sound waves to the ear on the frequency which we can hear. dear student, As the air moves, it carries energy out from the drum in all directions. Sound is like light in some ways: it travels out from a definite source.
