Chapter 38, Problem 38A

To determine

Whether the photons be more energetic or less energetic for larger value of Planck’s constant.

Explanation of Solution

Introduction:

The energy of the photon depends on the Planck’s constant and frequency of the incident light. If the frequency remains same then energy of the photon only depends on the Planck’s constant.

The energy of the Photon varies with the variation in the Planck’s constant for same frequency of the incident light. If the Planck’s constant become larger for the same frequency, then the energy of the photon of light beam also become larger.

Conclusion:

The energy of the photon of light beam become larger because the energy of the photon varies with the Planck’s constant for same frequency of the light.
