What is the frequency of a wave that has a wave speed of 120 m/s and a wavelength of 0.40 m

Here is your answer

Frequency= 300 Hz

REASON:

We know that,

Velocity= frequency × wavelength

Here,

Velocity= 120 m/s

and, wavelength= 0.40 m

So,

frequency= velocity/wavelength

f= 120/0.40

f= 300 Hz

cats appear to have glowing cat eyes because the back of their eyeballs includes a special reflective surface called the tapetum lucidum. this lets them see better during the night, giving them a much better vision.
