Answer 1

ANSWER—

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

• Refraction of light is the most commonly observed phenomenon, but other waves such as sound waves and water waves also experience refraction.

• For light, refraction follows Snell's law, which states that, for a given pair of media, the ratio of the sines of the angle of incidence θ1 and angle of refraction θ2 is equal to the ratio of phase velocities (v1 / v2) in the two media, or equivalently, to the indices of refraction (n2 / n1) of the two media.

Answer 2

Answer:

Hey user thanks for the points...✔️✔️

➡️ Refraction is a phenomenon of bending of ray of light or sound when passing from one medium to another.

➡️ Refraction is caused because of difference in densities of materials from which a wave/ Ray is travelling through.

➡️ Refraction of light is the most commonly observed phenomenon, but other waves such as sound waves and water waves also experience refraction.

➡️ The formula that describes refraction is also known as Snell's Law. The angle of refraction depends on the angle of incidence of the light, and the indexes of refraction of the two materials. The index of refraction of a material depends on the material's properties. The angles in Snell's Law are always measured relative to the normal to the barrier, which is perpendicular to the barrier's surface. The angles are measured in radians or degrees, and the indexes of refraction are unitless numbers.
