If a beam of light enters a substance with a higher density than air and at an angle, the light is refracted so that an object on the far side of the substance appears to be closer to the observer. If the density of the substance is lower than that of air, the light is refracted away from the observer and the object being viewed appears to be farther away.

ProfessorAn angle of refraction is the angle at which a light ray bends as it passes from one medium to another, such as from air to water or from air to glass. It is measured between the refracted ray and the normal (perpendicular line) at the point of incidence. The change in angle occurs due to the change in speed of light as it travels through different mediums.
Well the angle of refraction of light depends on refractive index of medium. You can calculate angle of refraction if you know the value of refractive index of medium. Suppose n is value of refractive index, i is ngle of incidence, r is angle of refraction then: sin(r)=sin(i)/n
When light travels from a medium with high refractive index to one with a lower refractive index, the ray bends away from the normal. If the incident ray arrives at close to tangential to the surface, the refracted ray may be refracted back into the medium with the higher refractive index. This is called total internal refraction and is a form of reflection.

What are the terms related to refraction of light?
terms realated to refraction of light are * interface * incident ray * refracted ray * point of incidence *normal *angle of incidence * angle of refraction *angle of deviation
How does the angle of incidence compared with the angle of refraction for sound?
For refraction, the general relationship is given by Snell's Law.
Are angle of incidence and angle of refraction proportional?
No, the angle of incidence and angle of refraction are not directly proportional. They are related through Snell's Law, which states that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is equal to the ratio of the velocities of light in the two mediums.
What will happen to the angle of refraction if the angle of incidence is made smaller for light passing from rarer to denser medium and how?
If the angle of incidence is made smaller for light passing from a rarer to a denser medium, the angle of refraction will also decrease. This is because of the law of refraction, which states that light bends towards the normal when moving from a rarer medium to a denser medium. Therefore, as the angle of incidence decreases, the angle of refraction will also decrease.
If a beam of light strikes a diamond at an angle of 45 degrees what is the angle of refraction?
The angle of refraction for a beam of light striking a diamond at an angle of 45 degrees will depend on the refractive index of the diamond material. The angle of refraction would be less than 45 degrees due to the bending of light as it enters the denser medium of the diamond.
