Question

A string vibrates with a frequency of 500 hz. If the distance between consecutive troughs is 10cm find the velocity

Answer 1

Answer:

50 m/s

Explanation:

Distance between two consecutive troughs is 10 cm, which indicates that λ = 10 cm (see image attached)

v = f λ

= 500 Hz × 10 cm

= 5000 cm/s

= 50 m/s
