Question

Which of the following is an example of electromagnetic waves?

• A. Alpha rays
• B. Beta plus rays
• C. Beta minus rays
• D. Gamma rays

Hint:

Electromagnetic radiation includes gamma rays, X-rays, ultraviolet, visible light, infrared, microwaves, and radio waves.

Answer 1

The Correct Option is D

Step 1: Recall the types of radiation.
- Alpha rays (\(\alpha\)): Helium nuclei (\(^4_2He^{2+}\)), which are charged particles. - Beta rays (\(\beta\)): Electrons (\(\beta^-\)) or positrons (\(\beta^+\)), which are also charged particles. - Gamma rays (\(\gamma\)): High-energy photons, which are electromagnetic waves.
Step 2: Conclusion.
Gamma rays are the only electromagnetic waves among the given options. They are part of the electromagnetic spectrum, unlike alpha and beta rays, which are particles.
Final Answer: \[ \boxed{\text{Gamma rays}} \]
