Answer 1

Answer:

• ight (3 × 108 m/s) travels faster than sound (340 m/s) in air. ... 1. Particles of the medium vibrate up and down at right angles to the direction in ... If 20 waves are produced per second, the frequency of sound waves is 20 Hz. ... (c) Wave speed in meters per second equals frequency in hertz multiplied by ...
