Question

What is true about X-rays and microwaves?

A. X-rays have greater speed than microwaves.
B.X-rays have greater amplitude than microwaves.
C. X-rays have greater frequency than microwaves.
D. X-rays have greater wavelength than microwaves.

Answer 1

you can discard A and B automatically since these are factors that do not depend on the wavelength of the wave.

however frequency does.

you'll want to find a diagram with the spectrum of wavelengths and find out which has greater wavelength or frequency
