Question

What kind of fringes do you expect to observe if white light is used instead of monochromatic light?

Solution

If the White light is used instead of monochromatic light then we see a sequence in which central fringe will be white and remaining will be coloured in VIBGYOR sequence.

Define a wavefront. Using Huygens’ principle, verify the laws of reflection at a plane surface.

In a single slit diffraction experiment, the width of the slit is made double the original width. How does this affect the size and intensity of the central diffraction band ? Explain.

When a tiny circular obstacle is placed in the path of light from a distant source, a bright spot is seen at the centre of the obstacle. Explain why

The refractive index of glass is 1.520 for red light and 1.525 for blue light. Let D₁ and D₂ be an of minimum deviation for red and blue light respectively in a prism of this glass. Then
