Answer: D) wavelength
Explanation:
The energy of an electromagnetc wave is given by the following formula:
(1)
Where:
is the Planck constant
is the frequency
Now, the frequency has an inverse relation with the wavelength :
(2)
Where is the speed of light in vacuum
Substituting (2) in (1) we have:
(3)
This means the amount of energy an electromagnetic wave carries depends on its wavelength (or its frequency), because the speed of light and are constant.
