A) different speeds starting from 0 to certain maximum.
B) same kinetic energy.
C) same frequency.
D) Both [b] & [c]
Correct Answer: A
Solution :
| Option [a] is correct. |
| Explanation: When a photon strikes a metal surface, the surface electrons come out with maximum speed and maximum kinetic energy. |
| But if the electron emission takes place from inner side of metal, then some energy of the electron is lost due to collision with other electrons and so their speed becomes less. |
| So, ultimately the electrons come out with different speeds. |
