How much energy is carried by a photon of light having frequency $110 \mathrm { GHz }$ ? $\left( h = 6.626 \times 10 ^ { - 34 } \mathrm {~J} \right.$. s)
A) $1.4 \times 10 - 22 \mathrm {~J}$
B) $1.3 \times 10 - 25 \mathrm {~J}$
C) $1.1 \times 10 - 20 \mathrm {~J}$
D) $7.3 \times 10 - 23 \mathrm {~J}$

Question

Quizplus · Accepted Answer

The energy $E$ carried by a photon can be calculated using the formula $E = h \nu$, where $h$ is Planck's constant and $\nu$ is the frequency of the photon. Substituting the given values, $E = 6.626 \times 10^{-34} \mathrm{J \cdot s} \times 110 \times 10^9 \mathrm{Hz} = 7.289 \times 10^{-23} \mathrm{J}$, which is closest to option D.
