Completion requirements
1. Give an idea about specific rotation
2. In an Young’s double slit experiment the separation of 12 fringe is observed 4mm. If the slit separation is 0.5mm and slit to screen distance is 1.2m, find the wavelength of light used in this experiment.
3. When a light of 6000Ǻ
incident on a diffraction grating, the diffracted angle for 3nd
order was measured 42˚. Find the no. of slits per cm of the grating.
