What is the energy of a blue light with a wavelength of 545 nm?
1 Answer
The energy of one photon of that light is 3.65 x
Explanation:
To find energy, you must know the frequency of the light. Since we are given wavelength we can use this equation: c=
(545nm)(m/
Plug in c and wavelength
3 x
solve for v by dividing both sides by the wavelength
v= 5.50 x
Now that we have frequency, you can use the equation: E= hv where E is energy per photon, h is planck's constant which is 6.626 x
E= (6.626 x
seconds cancel out leaving you with
E = 3.65 x
