guys please help me with this question

Explanation:
Refraction is the bending of a wave when it passes from one medium to another. The bending is caused due to the differences in density between the two substances.Laws of Refraction of Light
Laws of refraction state that:
The incident ray refracted ray, and the normal to the interface of two media at the point of incidence all lie on the same plane.
The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant. This is also known as Snell’s law of refraction.
sinisinr=constant
mark my answer brainlist ☺
Answer:
Refraction of light:
Refraction is the change in the direction of a light ray when passing from one medium to another.
Two laws of refraction of light are:
• The incident ray, the refracted ray and the normal to the interfaceof two media at the point of incidence all lie on the same plane.
• The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant. This is also known as Snell's law of refraction.
Sin i / Sin r = constant
Hope it helps...☺️
Plzz mark it as a brainliest if it helps.....✌️
