Question

1. What is the speed of a wave with wavelength 2.5m and frequency 20Hz?

Answer 1

Answer:

50m/s

Explanation:

v = f*w

Answer 2

Answer:

50 ans..

Explanation:

Data :

v = ?

wavelength= 2.5 m

f = 20 Hz

Formula:

speed = (frequency )(wavelength)

Solution:

v = ( 20 )( 2.5 )

v = 50 metre per second Ans ...........
