Calcualte the dispersive power for crown glass from the given data `mu_(v)=1.523` and `mu_(R) = 1.5145`

Text Solution

Verified by Experts

Here, `mu_(v)=1.523` and `mu_(r)=1.5145`
Mean refractive index,
`mu=(1.523+1.5145)/(2)=1.51875`
Dispersive power is given by,
`omega=(mu_(v)-mu_(r))/((mu-1))=(1.523-1.5145)/((1.51875-1))=0.1639`

Three thin prisms are combined as shown in figure. The refractive indices of the crown glass for red, yellow and violet rays are mu_r, mu_y and mu_v respectively and those for the flint glass are mu_r^', mu_y^' and mu_v^' respectively. Find the ratio A'/A for which (a) there is no net angular dispersion, and (b) there is no net deviation in the yellow ray.

When a ray of sun light passes through the prism, each colour of light has its own speed in the glass. The seven colours come out of the prism with different angles of deviation. Red deviates least and blue deviates maximum. Thus a prism can disperse a white light into seven colours which is called colour spectrum. For a thin prism, the angle of deviation is given as delta=(n-1)A . The angle of dispersion is given as phi=delta_(v)-delta_(r) . The dispersive power of a prism is omega=(phi)/(delta_("mean"))=(phi)/(delta_(y)) Using the above ideas, give answer the following questions. A prism has R.I. for violet and red n_(v)=1.523, n_(r)=1.5145 . If the angle of prism is A=2^(@) the dispersive power of the prism is :
