Explanation:
Given parameters:
Wavelength of photon = 827nm = 827 x 10⁻⁹m
Unknown:
Energy of the photon = ?
Type of radiation = ?
Solution:
The energy of a photon can be derived using the expression below:
E = [tex]\frac{h c}{wavelength}[/tex]
h is the Planck's constant = 6.63 x 10⁻³⁴m²kg/s
c is the speed of light = 3 x 10⁸m/s
Insert the parameters and solve;
E = [tex]\frac{6.63 x 10^{-34} x 3 x 10^{8} }{827x 10^{-9} }[/tex]
E = 2.4 x 10⁻¹⁹J
Type of radiation:
Near infrared radiation
