photon of green light has how much energy compared to a photon of orange light?

Question

Do lights of Red, orange and yellow have higher energy than green blue and violet?
how would you compare the energy of green light to orange light?
does the green light have less energy than orange light?

Answer 1

The energy contained within a single photon of light can be found using Planck's equations,
E = hv
Where E is the energy, h is Planck's constant, and v is the frequency of the light.

You can see that the higher the frequency of light, the higher the energy per photon.
Examining the spectrum of light one can see that green light (roughly a wavelength of 550 nm) has a higher frequency than orange light (roughly a wavelength of 650 nm).
Therefore, green light photons contain more energy than orange light photons.

Planck's constant = h = 6.626 E-34 J s

Answer 2

light = 6.626 × 10-34
