Dutchess · Answer 1

From the Electromagnetic Spectrum:

Radio, Micro wave, Infrared, Visible light, Ultra Violet, X rays, Y rays.

Only the Radio wave of wavelength 10³ m, has a positive power index, others have a negative exponent.

So these long waves form a smaller percentage.

Option A is correct. Others are not true.
