A 3000 W carbon dioxide laser emits an infrared laser beam with a wavelength of 10.6 μm. How many photons are emitted per second?

Answer :

The answer is photons are emitted per second [tex]n=1.599 \times 10^{23}$[/tex]

[tex]E=p x t......(i)[/tex]

and also

[tex]E=\frac{n h c}{\lambda}.......(ii)[/tex]

[tex]E=$ Energy$\\P=P_{\text {ower }}$$\\t=$ time[/tex]

[tex]$\begin{aligned} \frac{n h c}{\lambda} &=p t \\ n &=\frac{p_{\lambda t}}{h c} \end{aligned}$[/tex]

[tex]$n=\frac{3000 \times 10.6 \times 10^{-6} \times 1}{6.626 \times 10^{-3} \times 3 \times 10^{8}}$[/tex]

[tex]n=1.599 \times 10^{23}$[/tex] photons parsec

What is carbon dioxide emits?

  • Most of the greenhouse gas emissions from this industry are carbon dioxide [tex]$\left(\mathrm{CO}_{2}\right)$[/tex], although there are also minor emissions of nitrous oxide [tex]$\left(\mathrm{N}_{2} \mathrm{O}\right)$[/tex] and methane [tex]$\left(\mathrm{CH}_{4}\right)$[/tex].
  • These gases are generated when fossil fuels like coal, oil, and natural gas are burned to create power.
