When describing electromagnetic radiation, there is a(n) relationship between wavelength and frequency and the greater the frequency, the energy the electromagnetic radiation has.

a) direct; less

b) direct; more

c) inverse; more

d) inverse; less

Its actually C. I did the question on USA test prep and it said the correct answer was C.

C. Inverse; more

Explanation:

An electromagnetic radiation can be described by it wavelength or frequency or energy. These are related by:

c = λ f

where, c is the speed of light, λ is the wavelength of the light and f is the frequency.

E = h f

where E is the energy, h is Planck's constant and f is the frequency.

Thus, there is inverse relation between wavelength and frequency. As speed of light is constant in a given medium, with increase in frequency, wavelength decreases.

There is direct relationship between energy and frequency.

When frequency increases, Energy increases. Thus, greater the frequency, greater energy the electromagnetic radiation has.
