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

Respuesta :

Answer:

D) 1000 m/s

Explanation:

[tex]wavelength = \frac{velocity}{frequency}[/tex]

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.
