What do you understand by bond length? On what factors does it depend?

(a) How does the angle of deviation produced by a prism change with increase in the angle of incidence. Draw a curve showing the variation in the angle of deviation with the angle of incidence at a prism surface. (b) Using the curve in part (a) above, how do you infer that for a given prism, the angle of minimum deviation delta_("min") is unique for a given light.

How does the deviation produced by a prism depend on (i) the refractive index of its material, and (ii) the wavelength of incident light.

Assertion If angle of incidence in case of a prism is gradually increased, then deviation produced by prism will first decrease, then increase. Reason At minimum deviation, r_(1) =A/2 .
