Light passes successively through two polarimeters tubes each of length 0.29m . The first tube contains dextro rotatory solution of concentration 60kgm^-3 and specific rotation 0.01 rad m^2kg^-1 . The second tube contains laevo rotatory solution of concentration 30kg//m^3 and specific rotation 0.02 rad m^2kg^-1 . The net rotation produced is

Calculate the specific rotation of sugar solution from the following data: length of the polaimeter tueb=0.21 concentration of sugar solution = 80kgm^(-3) angle of rotation = 10^(@)

Light passes through a system of two crossed Nicol prisms between which a quartz plate cut at right angles to its optical axis is placed. Determine the minimum thickness of the plate which allows light of wavelength 436 nm to be complately cut off by the system and transmits half the light of wavelength 497 nm . The specific rotation constant of quartz for these wavelength is equal to 41.5 and 31.1 angualr degress per mm respectively.

A 300 mm long tube containing 60 cm^(3) of sugar solution produces an optical rotations of 10^(@) when placed in a saccharimeter. If specific rotation of sugar is 60^(@) calculate the quantity of sugar constained in te tube solution.
