The amplitude of an electromagnetic wave at a frequency f may assume any finite value one chooses, depending on how much energy is in the wave. True or false? (give best choice and explain briefly)
Homework Answers
In the wave theory it is stated that with energy the amplitude varies. If some energy of wave is absorbed the field strength tend to decrease due to which amplitude of the wave goes on decreasing. So energy carried by wave depends on the amplitude and vice-versa.
So the above statement is TRUE.
