Question

1) a microwave has a typical wavelength of about 0.1 meter. What us the comparable wavelength of a radio wave?

A) less than 0.1 meter

B) greater than 0.1 meter

C) equal to 0.1 meter

D) it depends on the frequency

Answer 1

higher frequency means shorter wavelength
so, which is which?

just look at any illustration of the electromagnetic spectrum
