Science MCQs

Refraction is the bending of light when it passes from one transparent medium to another.

Refraction happens when light travels from one medium to another with a different density.

Light rays bend at the water-air interface making the pencil appear bent.

The incident ray is the light ray approaching the boundary between two media.

The refracted ray is the ray that has bent while entering the second medium.

The normal is an imaginary line drawn perpendicular to the surface where light hits.

Light bends towards the normal when entering a denser medium like glass.

Light bends away from the normal when entering a less dense medium like air.

Angle of incidence (i) is the angle between the incident ray and the normal.

Angle of refraction (r) is the angle between the refracted ray and the normal.
