Question

If a 12m long wave has a frequency of 20 Hz how fast is it propagating

Answer 1

Answer:

240 m / s

Explanation:

Given:

Wavelength (λ) = 12 m

Frequency (ν) = 20 Hz

Velocity of wave (V) = ?

Solution:

We know that :

V = λ ν

⇒ V = 12 x 20

⇒ V = 240 m / s

Answer 2

the answer is 240 this will help u pls thank me
