What determines how light bends? Use the words: index refraction, incident angle, reflected angle, refracted angle, and color.

Expert Solution

When a light enters from a medium with less refractive index(opticallyrrarer medium) to a medium of more refractive index(opticallyddenser medium) then the ray will bend towards the normal. And if the light travels from a medium of more refractive index to a medium of less refractive index it will bend away from the normal.

The angle of refraction normally increases with angle of incidence upto a value.

The index of refraction depends upon the wavelength. Because refractive index is the ratio of speed of light in vacuum to the speed of light in medium.. And the frequency remains constant. So the color change also changes the velocity of the light ray. As a result the extension of refraction also changes.

When light enters from a optically denser medium to rarer medium at a particular angle of incidence the refracted ray will travel along the boundary of the two media. If the angle of incidence is increased the ray will totally internally reflected.
