Chapter 27, Problem 10A

Different bells and tuning forks have their own natural vibrations and emit their own tones when struck. How is this analogous to atoms, molecules, and light?

To determine

To explain: The analogy in context to atoms, molecules, and light.

Answer to Problem 10A

Vibrating electrons presents in atom and molecules that emits light.

Explanation of Solution

Introduction: Light is electromagnetic radiation. It has a speed of $3\times {10}^8\text{m/s}$ . The distance traveled by the light in one year is known as one light-year. One light-year is a unit of a distance.

Explanation: The electron presents in Atoms and molecules become excited by absorbing energy, and it also vibrates at distinctive frequencies. These vibrations of electron emit light.

Conclusion: Light is emitted by the atoms and molecules when the electrons vibrate.
