Two polaroids are placed at `90^(@)` to each other and the transmitted intensity is zero. What happens when one more polarid is placed between these two bisecting two bisecting the angle between them?

What is is plane polarised light ? Two polaroids are placed at 90^(@) to each other and the transmitted intensity is zero. What happens when one more polaroid is placed between these two, bisecting the angle betweeen them ? How will the intensity of transmitted light vary on further rotating the third polaroid ? (b) If a light beam shows no intensity variation when trasmitted through a polaroid which is rotated, does it mean that the light is un-polarised ? Explain briefly.

Two poalroids are placed at 90^(@) to eachother and the transmitted intensity is zero. What happens when one more polaroid is placed between these two bisecting the angle between them ? What will be the diraction of polarization of outcoming beam ?

Two polaroids are placed at 90^(@) to eachother and the transmitted intensity is zero. What happens when one more polaroid is placed between these two, bisecuting the angle between them. How will the intensity of transmitted light vary on further rotating the third polaroid ?

Two polaroids are placed at 90^(@) to eachother. What happens when (N - 1) more polaroids are inserted between them ? Their axes are equally spaced. How does the transmitted intensity behave for large N ?

Disuss the intensity of transmitted light when a polaroid sheet is rotated between two crossed polaroids ?

Two plane mirrors are at 45^(@) to each other. If an object is placed between them, then the number of images will be
