Draw a ray diagram showing the path of rays of light when it enters with oblique incidence: $(i)$ from air into water; $(ii)$ from water into air.

(N/A) When light travels from a rarer medium (air) to a denser medium (water),it bends towards the normal. In this case,the angle of refraction $(r)$ is less than the angle of incidence $(i)$.

The ray diagrams are provided in the image.
