A popular radio station broadcasts with a frequency of 94.7 MHz. What is the wavelength of the broadcast? (1 MHz = 1x106 Hz).

λ = 0.032×10² m

Explanation:

Given data:

Frequency of broadcasts = 94.7 MHz

Wavelength of broadcasts = ?

Solution:

Frequency of broadcasts = 94.7× 10⁶ Hz

Formula:

Speed of wave = frequency × wavelength

3×10⁸ m/s = 94.7× 10⁶ Hz × λ

λ = 3×10⁸ m/s /94.7× 10⁶ Hz

 Hz = 1/s

λ = 0.032×10² m
