Question

Find the speed of the sound wave? The time from the beginning to the end of the wave train is 1 second. Wavelength of the wave is 3 cm.

Answer 1

Speed of sound = wavelength * frequency

Let speed of sound be x

Frequency = 1/ time period

•

• • x = 0.03 * 1/1 = 0.03 m/s

Hope will help....
