Answer:
[tex]3.315 x 10^-19 J[/tex]
Explanation:
Using Eisten's formula, energy is a product of Plank's constant and photon frequency
E=hf
Where f represent frequency, h is Plank's constant and E is energy.
Substituting frequency with 5 x 10^14 Hz and
Planck's constant is 6.63 x 10^-34 J•s.
[tex]E=6.63 x 10^{-34} *5 x 10^{14}=3.315x10^{-19} J[/tex]
