Answer :
The wavelength of light is 62.8nm.
Wavelength:
The wavelength is the spatial period of a periodic wave- the distance over which the wave's shape repeats.
Formula to calculate Energy:
E = hc/λ
E = energy = 1.91 × [tex]10^{6}[/tex] J
h = 6.626 ×[tex]10^{-34}[/tex]
c = 3 × [tex]10^{6}[/tex]
Here we have to find the value of wavelength:
Putting the values in the equation,
λ = hc/ E
= ( 6.626 ×[tex]10^{-34}[/tex]) ( 3× [tex]10^{8}[/tex]) / 1.91 [tex]10^{6}[/tex]
= 62.8 nanometer
Therefore the wavelength of light is 62.8nm.
