Calculate the energy of a photon of electromagnetic radiation ateach of the following wavelengths.
632.8  (wavelength of red lightfrom helium-neon laser)

=

 

Part B

503  (wavelength of maximumsolar radiation)

=

 

 

Part C

0.0520  (a wavelength contained inmedical X-rays)

=

part A

-------

We know that Energy , E1 = hc / λ
Where

h = plank's constant = 6.625 * 10^-34 Js

c = speed of light = 3 * 10^8 m/s

λ = wave length = 632.8 * 10^-9 m

Plug the values we get E1 = 3.14*10^-19 J

part B

-------

We know that Energy , E2 = hc / λ
Where

h = plank's constant = 6.625 * 10^-34 Js

c = speed of light = 3 * 10^8 m/s

λ = wave length = 503 * 10^-9 m

Plug the values we get E2 = 3.95*10^-19 J

part C

-------

We know that Energy , E3 = hc / λ
Where

h = plank's constant = 6.625 * 10^-34 Js

c = speed of light = 3 * 10^8 m/s

λ = wave length = 0.0520 * 10^-9 m

Plug the values we get E 3= 3.82*10^-15 J
