COMEDK · Physics · 24. Electromagnetic Waves
The best waves for emission of electrons from a surface are
- A microwaves
- B ultraviolet rays
- C infrared rays
- D X-rays
Answer & Solution
Correct Answer
(D) X-rays
Step-by-step Solution
Detailed explanation
The best waves for emission of electrons from a surface are X-rays because when X-ray photon strikes a metal surface, then produce Compton or photoelectric effect more suitably.
