Question

Which of the following statements is true if the frequency of a light beam is increased while its intensity is held constant The speed of the photons is Increased. The energy of the photons is increased. The number of photons per unit time is increased. The wavelength of the light is increased. The probability of finding an electron in a given potential is directly proportion.il to: its energy. its momentum. its wave function. the magnitude squared of its wave function. the product of the position coordinate and the magnitude squared wave function. None of the above.

Explanation / Answer

Section II

I will write things that are true

Part 1

The photon energy according to the Planck equation E = h f

The light intensity is proportional to the number of photons

the speed of light is constant

so the only true answer is B

Part 2

In quantum mechanics the wave function squared corresponds to the probability density of finding the particle

the product of the position by the wave function squared is the average value of x

The answer is D
