Answer:

[tex]E = 6.63\times10^{-11} J[/tex]

Explanation:

We know that energy of a photon

E =hυ = hc/λ

h = planks constant,  = 6.63×10^{-34} J s

υ= frequency of the wave, c= speed of light, = 3×10^8 m/s

λ = wavelength = 3×10^{-15} m

[tex]E = [6.63\times10^{-34}\times3\times10^8]/3\times 10^{-15}[/tex]

[tex]E = 6.63\times10^{-11} J[/tex]
