STATEMENT- 1 When a glass prism is Immesed in water ,the deviation caused by prism decreases. STATEMENT 2 Refractive index of glass prism relative to water is less than relative to air.

Assertion: When a glass prism is immersed in water, the deviation caused by prism decreases. Reason: Refractive index of glass prism relative to water is less than that relative to air.

Assertion: When a glass prism is immersed in water, the devitation caused by prism decreases. Reason: Refractive index of glass prism relative ot water is less than that relative to air.

A student is performing an experiment with two triangular glass prisms. He places the first glass prism on its base. The second glass prism is placed upside down behind the first glass prism. When a beam of white light is allowed to fall on the first glass prism, then a patch of ordinary white light is obtained on a screen placed behind the second glass prism. (a) Draw a ray diagram to show the above· arrangement of two glass prisms and the light passing through them. (b) What is the function-of (i) first prism, and (ii) second prism, in this arrangement?
