Concept Introduction:
The distance between the two consecutive crests of a wave is called its wavelength.
Electromagnetic radiation is the type of energy that surrounds us and may lie in the visible region.
Modification or variation in amplitude is called amplitude modulation.
The wavelength of a radiation is given as follows:
Here,

Answer to Problem 7.1YT
Solution:
Explanation of Solution
Given information: The frequency of the radio signal is 840KHz.
First, the relationship between kilohertz and hertz is as follows:
Also, the relationship between hertz and cycle per second is as follows:
The wavelength of the radiation is calculated as follows:
Substitute
The wavelength of the electromagnetic radiation is
