Green light has a frequency of about 6.00×1014s−1. What is the energy of a photon of green light?

Respuesta :

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)
