Refraction Physics Math
Refraction is described mathematically by snell s law.
Refraction physics math. Angles between the ray and the line normal to the surface in the two media. The formula for refraction. If i is the angle of incidence and r is the angle of refraction then according to snell s law we have frac sin i sin r constant mu. It can also be stated as the ratio of the sines of the angles of incidence and refraction is equivalent to the ratio of phase velocities in the two media or equivalent to the reciprocal of the ratio of the indices of refraction.
Scroll down the page for more examples and solutions in using snell s law for refraction. N is the refractive index. Snell s law describes the path of least action between two points in different media. A bigger refractive index means a lower speed.
According to it the ratio of the sine of the angle of incidence to the sine of the angle of refraction will be a constant. Refraction and snell s law. C is the speed of light in vacuum and. θ 1 θ 2.
The ratio of the speed in a vacuum to speed in the medium is called the refractive index or index of refraction. Indexes of refraction of the two media. Its formula is based on snell s law. More physics video lessons math worksheets this is a series of free physics video lessons.
