Which of the following results is not true about photoelectric effect?
- A The electrons are ejected from the metal surface as soon as the beam of light strikes to the surface
- B The number of electrons ejected is proportional to the intensity or brightness of light.
- C There is a time lag between the striking of light beam and the ejection of electrons from the metal surface.
- D For each metal, there is a characteristic minimum frequency below which photoelectric is not observed.
Answer & Solution
Correct Answer
(C) There is a time lag between the striking of light beam and the ejection of electrons from the metal surface.
Step-by-step Solution
Detailed explanation
Regarding photoelectric effect, the statement of option-(c) is not correct. Because, the electrons are ejected from the metal surface as soon as the beam of light strikes to the surface.
