Answer:
[tex]E = 4.37 \times 10^{-19} J[/tex]
Explanation:
As we know that the wavelength of the photon is given as
[tex]\lambda = 454 nm[/tex]
[tex]h = 6.626 \times 10^{-34} Js[/tex]
[tex]c = 2.998 \times 10^8 m/s[/tex]
now we have
[tex]E = \frac{hc}{\lambda}[/tex]
now plug in all data in it
[tex]E = \frac{(6.626 \times 10^{-34})(2.998 \times 10^8)}{454 \times 10^{-9}}[/tex]
now we know that
[tex]E = 4.37 \times 10^{-19} J[/tex]
