enter your answer in the provided box.
how much more energy per photon is there in green light of wavelength 536 nm than in red light of wavelength
622 nm?
__× 10 __ j
(enter your answer in scientific notation.)

Answer : The correct answer is

Explanation :

For green light :

where,

E = energy of green light = ?

h = Planck's constant =

C = speed of light =

= wavelength of light = 536 nm =

Now put all the given values in the above formula, we get:

For red light :

where,

E = energy of red light = ?

h = Planck's constant =

C = speed of light =

= wavelength of light = 622 nm =

Now put all the given values in the above formula, we get:

Now we have to calculate the energy difference.

Therefore, the correct answer is
