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.

Draw a ray diagram to show the path of a ray of light passing obliquely from water to alcohol.

Draw a labelled ray diagram to show how a ray of light is refracted when it passes: a) From air into an optically denser medium. b) from an optically denser medium into air.

When light enters from air to water, then its

When a ray of light travelling in glass enters into water obliquely:

When a ray of light enters into water from air "………."

Draw a neat and labelled diagram to show the path of a ray of light in air and glass when the ray is incident obliqely on a glass slab. Show the (i) incident ray (ii) refracted ray (iii) emergent ray (iv) angle of incidence (v ) angle of refraction (vi) angle of emergence in the diagram. OR Draw a neat and labelled diagram to show refraction of light through a glass slab.
