Intensity of reflected is not equal to the intensity of the incident light. In generate, the reflection is least and transmission is highest at normal incidence. Some light is absorbed even by the best mirrors. Part of the wave is reflected in the direction OR, and part refracted in the direction OT. Now the intensity of the reflected light and transmitted light definitely depends on the angle of incidence. How much is reflected depends on properties of the mirror, wavelength of light and light polarization Intensity of reflected light increases with the angle. The angles that the incident, reflected and refracted rays make to the normal of the interface are given as θi, θr and θt, respectively. Both refraction and corneal refractive power were found to be correlated with light intensity. when a light beam is directed on a refracting medium, some of the light is refracted and some is reflected. On day 90 after hatching, exposure to light intensities of 10,000, 500, and 50 lux resulted in hyperopia of +11.97+/-3.7 (mean+/-SD) +7.9+/-4.08 and +0.63+/-3.61 diopters (D), respectively. In the diagram on the right, an incident plane wave in the direction of the ray IO strikes the interface between two media of refractive indices n1 and n2 at point O. Simple, single wavelength refraction consists of the incident beam, the reflected beam and a single refracted beam. When measuring the intensity of light, the integral under the intensity x wavelength function and the spectral sensitivity of the sensor itself is taken, and this area corresponds to the overall intensity. As the angle of incidence increases, reflection becomes higher and transmission becomes lower. During refraction, i.e. This information comes from the Fresnel equations.
