Snell's law of refraction ( wavelengths)
Description
When a ray of light hits the boundary between two transparent materials, it is divided into a reflected and a refracted ray.The law of refraction states that the refracted ray lies in the plane of incidence, and the sine of the angle of refraction divided by the sine of the angle of incidence is equivalent to the ratio of the wavelengths in the two media.
(The wavelength of a sinusoidal wave is the distance over which the wave’s shape repeats. Wavelength depends on the medium that a wave travels through).
Variables
| λ1 | Wavelength of the material of incidence (nm) |
| λ2 | Wavelength of the material of refraction (nm) |
| θ1 | Angle of incidence (degree) |
| θ2 | Angle of refraction (degree) |
