[a] Threshold frequency for the metal is \[1.2\,\,\times \,\,{{10}^{15}}Hz\] |
[b] Work function of the metal is \[4.968\text{ }eV\] |
[c] Maximum kinetic energy of photoelectrons corresponding to light of wavelength 100 nm is nearly \[7.4\text{ }eV\] |
[d] Photoelectric effect takes place with red light |
A) a, b
B) a, b, c
C) a, b, c, d
D) a, c, d
Correct Answer: B
Solution :
\[\frac{hc}{{{\lambda }_{0}}}\] \[\frac{hc}{\lambda }\,\,=\,\,\frac{hc}{{{\lambda }_{0}}}\,\,+\,\,K.{{E}_{\max }}\]You need to login to perform this action.
