The speed of an electromagnetic wave is a constant, 3.0 × 10 8m/s. the wavelength of a wave is 0.6 meters.
what is the frequency?
a.1.8 × 10 8hz
b.5.0 hz
c1.8 hz
d.5.0 × 10 8hz

Explanation :

It is given that,

Speed of the wave,

Wavelength of the wave,

We know that,

where

v is the speed of the wave

is the wavelength of the wave

f is the frequency of the wave

or

So, the correct option is (d).
