Answer: The energy of the infrared radiation is [tex]19.8\times 10^{-21}J[/tex]
Explanation:
The relationship between wavelength and energy of the wave follows the equation:
[tex]E=\frac{hc}{\lambda}[/tex]
E= energy
[tex]\lambda [/tex] = wavelength of the wave =[tex]1.0\times 10^{-5}m[/tex]
h = Planck's constant = [tex]6.626\times 10^{-34}Js[/tex]
c = speed of light = [tex]3\times 10^8m/s[/tex]
[tex]E=\frac{6.626\times 10^{-34}Js\times 3\times 10^8m/s}{1.0\times 10^{-5}m}[/tex]
[tex]E=19.8\times 10^{-21}J[/tex]
Thus energy of the infrared radiation is [tex]19.8\times 10^{-21}J[/tex]
