Question

A wave has a frequency of 240 hz and a wave length of 3.0 m. what is the speed of the wave

Answer 1

Answer:

c = f×w

c = 240 × 3

c = 720 m/s

Answer 2

Answer:

720.0 m/s

Step-by-step explanation:

The speed of the wave is

v = ( 240 ) ( 3.0 ) = 720.0 m/s

Explanation:

If  

n  is the frequency of the wave

λ  is the wavelength of the wave

v  is the speed of the wave,

the three quantities are related by

v = n λ

We have, n = 240 Hz

λ = 3.0

m v = ?

Substituting v = (240) * ( 3.0 )

= 720.0 m/s
