Question

5. All of the following statements about the photoelectric effect are correct, EXCEPT

A) The maximum kinetic energy of the photoelectrons depends on the intensity of the light

B) The photocurrent depends on the intensity of the light

C) The intensity of the light is a measure of the number of photons in the light.

D) The work function of the surface does not depend on the frequency of the light

E) The maximum kinetic energy of the photoelectrons depends on the frequency of the light

6. Which of the following revealed that the electron has a wavelength?

A) The photoelectric effect

B) Compton effect

C) Davisson and Germer’s experiment

D) Millikan’s oil drop experiment

E) Young’s double slit experiment

7. Which of the following revealed that light has a particle nature?

A) The photoelectric effect

B) Davisson and Germer’s experiment

C) Millikan’s oil drop experiment

D) Young’s double slit experiment

(5) expect option A

because since einstein's equation does not involue a factor representing intensity

the maximum kinetic energy of emitted electrons is independent of the intensity of the light

(6)ANS

THE Electron has wave length revealed by the experment is compton effect

(7)ANS

THE LIGHT HAS PARTICLE NATURE IS REVEALED BY THE PHOTO ELECTRIC EFFECT

BECAUSE THE WAVE THEORY OF LIGHT MISERABLY FAILED TO EXPLAIN PHOTO ELECTRIC EFFECT
