Question

A certain FM radio station broadcasts electromagnetic waves at a frequency of 9.05x10 Hz. These radio waves travel at a speed of 3.00x108 m/s. What is the wavelength of these radio waves?

Answer 1

Answer:

3.32 m

Explanation:

We have:

f = frequency of the electromagnetics waves = 9.05x10⁷ Hz (frequency of the electromagnetic waves of FM broadcast throughout the world)

c = is the speed of the electromagnetics waves = 3x10⁸ m/s (speed of light)

We can find the wavelength of the electromagnetics waves as follows:

$\lambda = \frac{c}{f}$

$\lambda = \frac{3 \cdot 10^{8} m/s}{9.05 \cdot 10^{7} s^{-1}} = 3.32 m$

Therefore, the wavelength  of a certain FM radio station broadcasts electromagnetic waves is 3.32 m.

I hope it helps you!
