Do radio waves and microwaves have longer or shorter wavelengths than visible light?

Radio and microwaves have longer wavelengths than visible light.

If you go take a look at the electromagnetic spectrum, you will be able to see that visible light waves have a higher frequency and a shorter wavelength ().

There is no reason to think the results are biased or not conducted properly but you should not assume the results are correct just because they were done in a laboratory so the answer would be c. it is likely to be reliable because the results support the conclusion presented.
