A ray of light impinges on a transparent material at some angle with the normal. If the material has a higher index of refraction, as it enters, the ray will .

Bend to make a smaller angle with the normal

Explanation:

If a material has a higher index of refraction, when light enters the material, it angle of refraction will be smaller than it angle of incidence, the light will then be refracted towards the normal surface. refraction occurs when light hits the boundary between two different materials

Therefore,the ray of light impinging on the transparent material will bend toward a smaller angle with the normal
