Refractive index of glass for red and vi...

Refractive index of glass for red and violet colors are 1.50 and 1.60, respectively. Find:
a. The refractive index for yellow color, approximately
b. Dispersive power of the medium.

Text Solution

Verified by Experts

a. `mu_(y)=(mu_(v)+mu_(r))/(2)=(1.6+1.5)/(2)=1.55`
b. Dispersive power:
`omega=(mu_(v)-mu_(r))/(mu_(y)-1)=(1.6+1.5)/(1.55-1)=(2)/(11)`
