What will you observe if
You look at an unpolarized source of light through a polarizer ?

What will you observe if You look at the source through two polarizers and rotate one of them around the path of light for one full rotation ?

What are primary sources of light?

What are coherent sources of light ?

When unpolarized light is passed through a polarizer , its intensity

When its unpolarized light is passed through a polarizer, its intensity

What are secondary sources light?

What will you observe if Instead of rotating only one of the polaroid , you rotate both polaroids simultaneously in the same direction ?

How did you observe microbes?

What will you observe when calcium is treated with water?

Explain polarisation of light (with a diagram) and also explain, unpolarised light passing through two polarizers. Derive Malus’ Law.
