If a crown glass prims of refracing angle `10^(@)` have refractive indices for red and violet rays `1.514` and `1.523` respectively then find the dispersion caused by a crown glass prism.A. `0.07^(@)`B. `0.08^(@)`C. `0.09^(@)`D. `0.10^(@)` |
Answer» (c) We know ,angular dispersion `=delta_(v)-delta_(R)=(mu_(v)-mu_(R))A=(1.523-1.514)xx10^(@)` `=0.009xx10^(@)=0.09^(@)` |
