Principle Of Deliberation

Heisenberg's uncertainty principle is the direct consequence of (i) wave nature of radiation (ii) wave-particle dualoty of radiation (iii) particle nature of matter (iv) wave-particle duality of matter

A tube of length l = 26 cm is filled with benzence and placed in a longitudinal magnetic field of a solenoid positioned between two Polaroids. The angle between the principle directions of the Polaroids is equal to 45^(@) . Find the minimum strength of the magnetic field at which light of the wavelength 589 nm propagates through that system only in one direction (optical value). What happens if teh idrection of the given magnetic field is changed to the opposite one?
