Answer: [tex]3.97(10)^{-19}J[/tex]
Explanation:
The energy [tex]E[/tex] of a photon is given by:
[tex]E=h\nu[/tex] (1)
Where:
[tex]h=6.626(10)^{-34}\frac{m^{2}kg}{s}[/tex] is the Planck constant
[tex]\nu=6(10)^{14}s^{-1}[/tex] is the frequency of green light
Solving (1):
[tex]E=(6.626(10)^{-34}\frac{m^{2}kg}{s})(6(10)^{14}s^{-1})[/tex] (2)
[tex]E=3.9756(10)^{-19}\frac{m^{2}kg}{s^{2}}=3.9756(10)^{-19}J[/tex] (3)
