Question

Which statement correctly compares radio waves and microwaves?

A. Radio waves have shorter wavelengths and lower frequencies than microwaves.
B. Radio waves have longer wavelengths and higher frequencies than microwaves.
C. Radio waves have longer wavelengths and lower frequencies than microwaves.
D. Radio waves have shorter wavelengths and higher frequencies than microwaves.

Answer 1

C. Radio waves have longer wavelengths and lower frequencies than microwaves.

Step-by-step explanation:

Radio waves and microwaves are both electromagnetic waves. They do not require a medium for their propagation.

These waves are produced as result of the vibration between electric and magnetic fields perpendicular to one another.

• On the electromagnetic spectrum, the waves are listed from left to right
• Along the spectrum, wavelength increases as frequency decreases.
• Energy also decreases to the right on the spectrum.
• Since microwaves comes before radio waves, they have shorter wavelength and higher frequency than micro waves.
