A beam of ultraviolet light of wavelength 300 nm and intensity 1.0 watt/m2 falls on the surface of a photo sensitive material. If one percent of the incident photons produce photoelectrons then the number of photoelectrons emitted from an area of 1.0 cm2 is approximately
- 2.13 x 1011 per sec
- 1.51 x 1012 per sec
- 4.12 x 1013 per sec
- 9.61 x 1014 per sec
Answer
(A) 2.13 x 10 11 per sec
