Which of the following is not an EM wave ?
- A X-rays
- B Gamma rays
- C Microwaves
- D Cathode rays
Answer & Solution
Correct Answer
(D) Cathode rays
Step-by-step Solution
Detailed explanation
Cathode rays are not electromagnetic waves; they are streams of fast-moving electrons (particles with mass and charge). In contrast, X-rays, Gamma rays, and Microwaves are all forms of photons that belong to the electromagnetic spectrum. D) Cathode rays.
