Teaching NVS PGT 2024 Test Series Physics Dual Nature: Photon and Matter Waves The Photoelectric Effect
In a photoelectric effect experiment a light of frequency 1.5 times the threshold frequency is made to fall on the surface of photosensitive material. Now if the frequency is halved and intensity is doubled, the number of photo electrons emitted will be:
1
Doubled
2
Quadrupled
3
Zero
4
Halved
