theta is the optical rotation produced by sugar solution of concentration C and taken in a glass tube of length 0.2 m and radius r . Then the solution is transferred to another glass tube of length 0.3 m and radius r and the remaining space is filled with distilled water. The optical rotation produced by this solution is

A cylindrical tube of light 0.2m and radius R with sugar solution of concentration 'C' produce a rotation of theta in the plane of vibration of a plane polarized light. The same sugar solution is transferred to another tube of length 0.3m of same radius. The remaining gap is filled by distilled water. Now the optical rotation produced is

Specific rotation of sugar solution is 0.5 deg m^2 kg^-1 * 200 kg m^-3 of impure sugar solution is taken in a sample polarimeter tube of length 20 cm and optical rotation is found to be 19^@ . The percentage of purity of sugar is

A glass tube is open at both the ends.A tuning fork of frequency f resonates with the air column inside the tube.Now the tube is placed vertically inside water so that half the length of the tube is filled with water.Now the air column inside the tube is in unison with another fork of frequency f'. Then

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