Vedclass · Answer

(B) The energy of a photon is given by the formula $E = h
u$,where $E$ is the energy,$h$ is Planck's constant,and $
u$ is the frequency.First,convert the energy from electron-volts $(eV)$ to Joules $(J)$:$E = 100 \ eV = 100 	imes 1.6 	imes 10^{-19} \ J = 1.6 	imes 10^{-17} \ J$.Now,substitute the values into the formula:$1.6 	imes 10^{-17} = 6.6 	imes 10^{-34} 	imes 
u$.Solving for $
u$:$
u = \frac{1.6 	imes 10^{-17}}{6.6 	imes 10^{-34}} \approx 0.2424 	imes 10^{17} \ Hz = 2.42 	imes 10^{16} \ Hz$.Thus,the correct option is $B$.

The frequency of a photon having energy $100 \ eV$ is $(h = 6.6 \times 10^{-34} \ J \cdot s)$.
