Vedclass · Answer

(B) The energy of a photon is given by the formula $E = hf$,where $E$ is the energy,$h$ is Planck's constant,and $f$ is the frequency.First,convert the energy from $eV$ to Joules: $E = 100 \ eV = 100 	imes 1.6 	imes 10^{-19} \ J = 1.6 	imes 10^{-17} \ J$.Now,rearrange the formula to solve for frequency: $f = \frac{E}{h}$.Substitute the values: $f = \frac{1.6 	imes 10^{-17} \ J}{6.62 	imes 10^{-34} \ J \cdot s}$.$f \approx 0.2417 	imes 10^{17} \ Hz$.$f = 2.417 	imes 10^{16} \ Hz$.

The frequency of a photon with energy $100 \ eV$ is ........... $Hz$. (Given: $h = 6.62 \times 10^{-34} \ J \cdot s$,$1 \ eV = 1.6 \times 10^{-19} \ J$)
