Which of the following statements is incorrect? Group of answer choices The product of wavelength and frequency of electromagnet
morpeh [17]

Answer: Option (b) is the correct.

Explanation:

It is known that energy is directly proportional to frequency.

Mathematically,              E \propto \nu

or,                           E = h \times \nu ............ (1)

where,     E = energy

                h = Plank's constant

              \nu = frequency

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

Also,     \nu = \frac{c}{\lambda} ......... (2)

where,          c = speed of light

                 \lambda = wavelength

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

                 E = h \times \nu

                 E = h \times \frac{c}{\lambda}

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.
