Question

What do radio waves and microwaves have in common?

Both are at the side of the spectrum that has the shortest wavelengths.

Both are at the side of the spectrum that has the lowest radiant energy.

Both are at the side of the spectrum that has the lowest frequency.

Both are found next to visible light on the electromagnetic spectrum.

Answer 1

Both are at the side of the spectrum that has the lower frequency

Answer 2

Answer: Both are at the side of the spectrum that has the lowest frequency.

Explanation:-

Electromagnetic wave is defined as the wave which is associated with both electrical and magnetic component associated with them. They travel with the speed of light.

Both radio and microwaves are electromagnetic waves which are adjacent to each other in electromagnetic spectrum towards lower frequency and higher wavelength.

The relationship between wavelength and frequency of the wave follows the equation:

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

where,

$\nu$ = frequency of the wave

c = speed of light  

$\lambda$ = wavelength of the wave
