Chapter 19, Problem 8A
Interpretation Introduction

Interpretation:The best characterization of a gamma (γ) ray has to be given.

Concept introduction:Gamma rays are form of energy that does not have any mass or charge. The symbol of gamma ray is γ. These are produced by supernova explosions and by decay of radioactive materials.

Answer to Problem 8A

The best characterization of a gamma (γ) ray is a high-energy photon of light. The correct option is (e).

Explanation of Solution

Light with shortest wavelengths and higher energy frequency in the electromagnetic spectrum is called as gamma radiation/gamma rays. They are one form of energy with zero mass and no charge. They travel at the speed of light. High-energy photon of light is the best characterization to identify a gamma ray. The correct option is (e).

Conclusion

Oxygen nucleus O816, is stable, hence it is not used to characterize gamma rays. Option (a) is incorrect.

Helium nucleus is an alpha particle (H24e), hence it is not used to characterize gamma rays. Option (b) is incorrect.

A particle with the same mass as an electron but with a positive charge is known as positron. Positron (e+10) cannot be used to characterize a gamma ray. Option (c) is incorrect.

An electron is a subatomic particle with negligible mass with negative charge (e). They are not used in the characterization of gamma ray and hence, option (d) is incorrect.
