State the plane of polarization.

Rotation of plane of polarization under influence of magnetic field called Faraday effect was conformed by

In the case of light waves the angle between plane of vibration and plane of polarization is

In the propagation of electromagnetic waves the angle between the direction of propagation and plane of polarization is

Terpinen - 4 - ol is an active ingredient in tea tree oil has the following structure The correct observations for terpinen - 4 - ol is/are I. It rotates the plane of plane polarized light. II It does not rotates the plane of plane polarized light III. On reaction with NaBr an H_2SO_4 , it gives a di bromo compound IV On ozonolysis it gives a compound with molecular formula C_10H_18O_3 .

Fig. shows a coil wound around a soft iron bar XY. State the polarity at the ends X and Y as the switch is pressed.

Draw the structure and state polar and non-polar nature of (a) CH_(4) (b) SO_(3) (c ) CHCl_(3).

A plane polarized light is incident on an analyser and when it is rotated to complete one rotation, one observes
