Question

A light ray hits a particle that is part of a solid. The ray is absorbed by the particle.

What will happen?

1). The particle will vibrate faster.

2 ) The particle stops all motion.

3). The mass of the particle will get bigger.

4) The particle will not be affected.

Answer 1

Answer: The particle will vibrate faster.

Explanation: When a light ray is absorbed by a particle, its energy is transferred to the particle. This additional energy causes the atoms in the particle to vibrate faster, which results in an increase in the particle's temperature. As a result, option 1, which states that the particle will vibrate faster, is the correct answer. Options 2, 3, and 4 are not applicable in this case.
