Answer 1

Answer:

refraction is the change in direction of a wave passing from one medium to another or from a gradual change in the medium.

Answer 2

Explanation:

1.Refraction is the bending of light (it also happens with sound, water and other waves) as it passes from one transparent substance into another. This bending by refraction makes it possible for us to have lenses, magnifying glasses, prisms and rainbows.

2.Why does refraction happen?

Ans.Refraction happens because the speed of the wave changes. Light travels slower (compared to its speed in air) in a more dense material like glass. ... Note that refraction doesn't happen if the waves cross the boundary at an angle of 90° (called the normal).

3.The incident ray, the normal and the refracted ray at a point of incidence all lie in the same plane. ... [for any two mediums, the ratio of the sine of angle of incidence to the angle of sine of refraction is constant which is called refractive index.] An incident ray passing through the normal always goes straight.
