Question:
Which of the following are not electromagnetic waves?
Which of the following are not electromagnetic waves?
Show Hint
Electromagnetic waves include a wide spectrum such as gamma rays, X-rays, and light, but \( \beta \)-rays are particles, not waves.
Updated On: Jan 12, 2026
- Cosmic rays
- Gamma rays
- \( \beta \)-rays
- X-rays
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Identify the nature of electromagnetic waves.
Electromagnetic waves include gamma rays, X-rays, and cosmic rays. However, \( \beta \)-rays are not electromagnetic waves; they are high-energy electrons emitted from radioactive decay.
Step 2: Conclusion.
Thus, \( \beta \)-rays are not electromagnetic waves.
Final Answer: \[ \boxed{\beta \text{-rays}} \]
