Question

If the frequency of wave is 400 Hz and its

wavelength is 2.5 m, what is the velocity?
a 3000 km/s
b 100 m/s
C 10000 m/s
d 1000 m/s

Answer 1

D) 1000 m/s

Step-by-step explanation:

`wavelength = (velocity)/(frequency)`

You have the wavelength and frequency, you just need to solve for velocity. You can do this by multiplying each side of the equation by frequency.

Hope this helps.
