  • How the Eye Detects Light - Changing minds

    A light detector (your eye) has an area of 2.00 x 10-6 m2 and absorbs 80% of the incident light, which is at wavelength 500 nm. The detector faces an isotropic source, 3.00 m from the source. If the detector absorbs photons at the rate of exactly 4.000s-1 at what power does the emitter emit light?

  • The human eye is similar to other light detectors.

    2021-6-10 · Fresnel's law of reflection states that the fraction of light reflected for normal incidence is: r = (n-1) 2 (n+1) 2, where n is the ratio of the refractive indexes of the two media. If n = 1.5 for air and glass, then r = 4% for each surface. Two filters separated by air transmit 8% less than two connected by optical cement (or even water).
