In a certain spectrum produced by a glass prism od dispersive power `0.031`, it was found that `mu_(r ) = 1.645 and mu_(b) = 1.665`. What si the refractive index for yellow colour ?
In a certain spectrum produced by a glass prism of dispersive power 0.031 , it was found that mu_r = 1.645 and mu_b = 1.665 . What is the refractive index for yellow colour ?
In a certain spectrum produced by a glass prism of dispersive power 0.0305, it is found that the refractive index for the red ray is 1.645. and that for the violet ray is 1.665 . What is the refractive index for the yellow ray?
Calculate the dispersive power for crown glass from the given data mu_(v)=1.523 and mu_(r)=1.5145 .
Calculate the dispersive power of crown glass where mu_(V)=1.522 and mu_(R)=1.514 .
If mu_(v)=1.530 and mu_(R)=1.5145 , then disperisve power of a crown glass is
The angular dispersion produced by a prism of angle 5^@ is [mu_v = 1.665, mu_r = 1.645]
A deviation of 2^(@) is produced in the yellow ray when prism of crown and flint glass are achromatically combined. Taking dispersive powers of crown and flint glass as 0.02 and 0.03 respectively and refractive index for yellow light for these glasses are 1.5 and 1.6 respectively. The refracting angles for crown glass prism will be ........ @ (in degree). (Round off to the Nearest Integer)
An achromatic prism is made by crown glass prism (A_(c) = 19^(@)) and flint glass prism (A_(F) = 6^(@)) . If .^(C)mu_(y) = 1.5 and .^(F)mu_(v) = 1.66 , then resultant deviation for red coloured ray will be
An achromatic prism is made by combining two prisms P_(1)(mu_(v)=1.523,mu_(r)=1.515) and P_(2)(mu_(v)=1.666,mu_(r)=1.650) Where mu represents the refractive index if the angle of the prism P_(1) is 10^(@) then the angle of the prism P will be
