To determine

To Choose: The correct option.

Answer to Problem 7STP

The correct option is (A).

Explanation of Solution

Introduction:

Light is an electromagnetic wave. Light consists of photons. The wavelength of visible light is $400-700\text{}\text{nm}$ .

Newton’s law are basically for motion, gravitation and so on. He didn’t explain about the behavior of light. Galileo did maximum of his work based on astronomy. Hertz experiment is about the study of nature of light not behavior of light. Therefore, the options (B),(C) and (D) are incorrect.

De-Broglie proposed that dual nature of light and proposed his hypotheses while Einstein supported the theory relating to the particle from light in photoelectric effect experiment. So, the correct option is (A).

Conclusion:

Hence, option (C) has explained accurately the given phenomenon.
