To find the specific rotation of sugar solution by using Laurent’s Half Shade Polarimeter.
The specific rotation of sugar solution is determined by the formula; S = θ / LC where ‘θ’ is the rotation produced in degree, L is the length of the tube in the decimeter (1 decimeter = 10 cm) and C is the concentration of the active substance in gm/cc in the solution.
If length of the solution (tube) is in cm then the formula will be; S = 10θ / LC also, C = mass of the substance (M) / volume (V). So, specific rotation = (10 X θ X V) / (L X M)
The unit of specific rotation is degree/(decimeter) x (gm/cm^3 ).
Ans. No, they have longitudinal nature, made only by one component, no transverse components.
Ans. An imaginary plane that is parallel to the electric vector components or vibrations is known as a plane of vibration.
Ans. It acts as a polarizer (through which plane-polarized light we obtain) and an analyzer (to detect the plane-polarized light).
Ans. Those substances which rotate the plane of polarization in the clockwise direction when the observer faces the source of light. Known also as right-handed substances.
Ans. thickness of the substance concentration of the solution temperature wavelength of light used
