Chapter 13, Problem 2RAT

Solution

To determine: The correct option for the statement "Strictly speaking, the photons of light that shine on glass are".

Answer:

The correct option for the statement "Strictly speaking, the photons of light that shine on glass are" is option (b).

Explanation:

When the light strikes on glass, there is a transformation of energy between light and molecules (electrons) of glass. After transmission of energy by light, the energy of electrons increases and they start vibrating.

Due to the vibration of these electrons, they either emit photons or transfer the energy as heat. If the electrons emit photons, they will shine on the glass.

Thus, the photons of light that shine on the glass are not the ones that travel through and exit the other side.

Conclusion:

Therefore, the correct option for the statement "Strictly speaking, the photons of light that shine on glass are" is option (b).
