Answer to Problem 1A

Photon is the particle of light.

Explanation of Solution

The fundamental unit of light or electromagnetic radiation is called photon. A photon has a zero-rest mass and contains 1 quanta of energy. In a vacuum, it travels with the speed of 3×108m/s .

The photon’s energy is,

  E=hυ

Where, h is the Planck’s constant

  υ is the frequency of the light radiation

Conclusion:

The photon is a particle of light and quanta of energy.

(b)

To determine

To Explain: The photons are consistent as particle or wave.

Answer to Problem 1A

Particle theory of light.

Explanation of Solution

Light behaves as wave as well as particle. As per particle theory, light is composed of the tiniest particles called the photons. So, the photons are more consistent with the particle theory of light.

Conclusion:

Photons are more consistent with the particle theory of light.
