Question

According to the electromagnetic spectrum,

a. long-wave radiation occupies a smaller percentage than short-wave radiation
b. gamma rays and x-rays have long wavelengths.
c. visible light waves have wavelengths of less than 1 micrometer.
d. ultraviolet light waves have some of the longest wavelengths.

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.

Answer 2

a. long-wave radiation occupies a smaller percentage than short-wave radiation
