Question

A wave has a frequency of 23.0 Hz and a wavelength of 14.9 m. What is the velocity of the wave?

1.54 m/s
8.1 m/s
37.9 m/s
343 m/s

Answer 1

343 m/s

Step-by-step explanation:

There is a formula to calculate the velocity of a wave given the frequency and wavelength.

Velocity = Frequency × Wavelength

v = f λ

v = 23 × 14.9

v = 342.7 ≈ 343

Answer 2

343 m/s

Step-by-step explanation:

Velocity Formula (Wave): v = fλ

v - velocity

f - frequency

λ - wavelength

We are given f = 23.0 and λ = 14.9. Simply plug it into the formula:

v = 23.0(14.9)

v = 342.7

v ≈ 343
