Question

Einstein's photoelectric equation is:

a) ${\displaystyle E_{\text{max}}=h\lambda - {\phi }_0}$

b) ${\displaystyle E_{\text{max}}=\frac{hc}{\lambda } {\phi }_0}$

c) ${\displaystyle E_{\text{max}}=hv+{\phi }_0}$

d) ${\displaystyle E_{\text{max}}=\frac{hv}{\lambda }+{\phi }_0}$

Answer 1

${\displaystyle E_{\text{max}}=\frac{hc}{\lambda } {\phi }_0}$

∵ ${\displaystyle hv+{\varphi }_0+E_{\text{max}}}$
