Which of the following statements is incorrect? group of answer choices the product of wavelength and frequency of electromagnetic radiation is a constant. as the energy of a photon increases, its frequency decreases. as the wavelength of a photon increases, its frequency decreases. as the frequency of a photon increases, its wavelength decreases. as the wavelength of a photon increases, its energy decreases.

Option (b) is the correct.

Explanation:

It is known that energy is directly proportional to frequency.

Mathematically,              

or,                           E = ............ (1)

where,     E = energy

                h = Plank's constant

              = frequency

This relation shows that higher is the energy then more will be the frequency of electrmagnetic radiation.

Also,     ......... (2)

where,          c = speed of light

                  = wavelength

Therefore, substituting value of from equation (2) into equation (1) as follows.

                 E =

                 E =

This relation shows that higher is the energy then lower will be the wavelength.

Thus, we can conclude that as the energy of a photon increases, its frequency decreases, is incorrect statement.
