Question

Electromagnetic radiation is more common than you think. Radio and TV stations emit radio waves when they broadcast their programs; microwaves cook your food in a microwave oven; dentists use X rays to check your teeth. Even though they have different names and different applications, these types of radiation are really all the same thing: electromagnetic (EM) waves, that is, energy that travels in the form of oscillating electric and magnetic fields.

Answer 1

Step-by-step explanation:

1. They have different wavelengths - Because These radiations form a spectra that differs by the size of the wavelength.

2. They have different Frequencies (f) that is frequency = 1/ wavelength

(f = 1/wavelength)

3. They propagate at different speed though a non vacuum media (non vacuum media affect the speed based on the wavelength)
