COMEDK · Physics · 24. Electromagnetic Waves
Which of the following is an electromagnetic wave?
A. Sound waves
B. Alpha rays
C. Beta rays
D. Gamma rays
- A D
- B B
- C C
- D A
Answer & Solution
Correct Answer
(A) D
Step-by-step Solution
Detailed explanation
Electromagnetic waves are waves that do not require a material medium for propagation and consist of oscillating electric and magnetic fields. Sound waves are mechanical waves requiring a medium. Alpha rays consist of helium nuclei, and beta rays consist of high-speed electrons,…
