The wavelength is represented by λ
[tex]\lambda\text{ = 5.20 }\times10^{-7}m[/tex]The speed of light is represented by c
[tex]c\text{ = 3 }\times10^8m\text{ /s}[/tex]The planck's constant is given as:
[tex]h\text{ = 6.6}3\text{ }\times10^{-34}Js[/tex]The energy of light is calculated using the formula below:
[tex]E\text{ = }\frac{hc}{\lambda}[/tex]Substituting the values of h, c, and λ into the formula above:
[tex]\begin{gathered} E\text{ }=\text{ }\frac{6.63\times10^{-34}\times3\times10^8}{5.20\times10^{-7}} \\ E\text{ = }3.825\times10^{-19}J \end{gathered}[/tex]The energy is therefore:
[tex]3.825\times10^{-19}J[/tex]
