Question

Which statement is true about the energy of electromagnetic radiation?
A.the frequency of the emmited radiation is inversely proportional to its energy.
B.the frequency of the emitted radiation is directly proportional to its energy
C.the wavelength of the emitted radiation is directly proportional to its energy.
D.the amplitude of the emitted radiation is inversely proportional to its energy.

Answer 1

the lower the frequency, the higher the wavelength, and the lower the energy
the higher the amplitude, the higher the energy

Answer 2

So its???

Answer 3

We don't give direct answer here, so I'm giving you information to help you.
A direct proportion means that as one thing increases so does the other.
An inverse proportion means that as one thing increases the other decreases.
Only one of the above is true, and you should be able to figure which from the info given.

Answer 4

Is it D

Answer 5

Amplitude of a wave refers to the height of the wave...

In the case of light waves... higher amplitude means brighter light ... brighter light means more energy

So, amplitude can't be INVERSELY proportional to energy:
The higher the amplitude, the higher the energy.
