Question

In the propagation of light waves, the angle between the plane of vibration & plane of polarisation is:

• A. 0${}^0$
• B. 90${}^0$
• C. 45${}^0$
• D. 80${}^0$

Answer 1

Answer: (B)

90${}^0$

The plane of polarisations is that plane in which there is no vibration. While a plane including the direction of light propagation and the direction of electric field is called the plane of vibration. The angle between them is ${90}^o$.
