🤓 Based on our data, we think this question is relevant for Professor Korzeniewski's class at TTU.
We’re being asked how many photons of blue light with a wavelength of 475 nm are needed to trigger the optic nerve.
Recall that the energy of a photon (E) is given by:
h = Planck’s constant (6.626 × 10–34 J • s)
v = frequency (in s–1)
Also, recall that the frequency (v) and wavelength (λ) are related:
c = speed of light (3.0 × 108 m/s)
The optic nerve needs a minimum of 2.0 x 10−17 J of energy to trigger a series of impulses that eventually reach the brain. How many photons of blue light (475 nm) are needed?
