A typical 100-watt light bulb consumes 100 j of energy per second. If a light bulb converts all of this energy to 400 nm light

VladimirAG [237]

The missing question is: how many photons are produced per second?

Answer:

$2.0\cdot 10^{20}$

Explanation:

The energy of a photon is given by

$E_1 = \frac{hc}{\lambda}$

where

h is the Planck constant

c is the speed of light

$\lambda$ is the wavelength of the photon

In this problem, the photons have wavelength

$\lambda = 400 nm = 400 \cdot 10^{-9} m$ , so each photon has an energy of

$E_1 = \frac{(6.63\cdot 10^{-34})(3\cdot 10^8)}{400\cdot 10^{-9}}=4.97\cdot 10^{-19} J$

The total energy emitted by the bulb in 1 second is

E = 100 J

Therefore, the number of photons emitted per second is

$n=\frac{E}{E_1}=\frac{100}{4.97\cdot 10^{-19}}=2.0\cdot 10^{20}$
