Question

PHOTO ELECTRIC EFFECT
26. When a metal is irradiated with light of
frequency 4.0 x1016,1 the photo electrons
emitted had six times the K.E as the K.E of photo electron emitted when the metal was irradiated with light of frequency 2 x 1016. calculate the critical frequency of the metal​

Answer 1

Answer:

HI

When a certain metal was irradiated with light of frequency 4.0×1019s-1 the photoelectrons emitted had three times the kinetic energy as the kinetic energy of photoelectrons emitted when the metal was irradited with light of frequency 2.0×1016s-1 .
