Question

Sorry if i picked the wrong subject

Electromagnetic waves are classified into forms such as radio waves, microwaves, and infrared waves, based on the amount of energy they carry. Which property of an electromagnetic wave determines the level or amount of energy it carries?
A) speed
B) intensity
C) phase
D) wavelength

Answer 1

D

Step-by-step explanation:

speed is constant in a certain medium.

phase is not directly related to the energy.

intensity and wavelength both determin amount of energy carried by the wave. however, in this question in first examples wavelength is pointed out. I guess D is the correct answer.

For B and D:

`energy = \sqrt{ (2 * i)/(c * \: epsilon ) } \: \: \: \\ energy = (hc)/(lambda)`

the first one is relation between intensity (i) and energy.

the second one is the relation between wavelength (lambda) and energy.
