A single slit diffraction pattern is obtained using a beam of red light. What happens if the red light is replaced by the blue light?

For a given single slit,the diffraction pattern is obtained on a fixed screen,first by using red ligth and then with blue light.In which case,will the central maxima,in the observed diffraction pattern,have a larger angular width?

What will be the effect on the interferece fringes,if red light is replaced by blue light?

Draw the diffraction pattern due to a single slit by a monochromatic light.

How does the power of a convex lens vary if the incident red light is replaced by violet light?

What two main changes in diffraction pattern of a single slit will you observe,when the monochromatic source of light is replaced by a source of white light?

Red light differes from blue light in its

What is diffraction of light?

Red light is incident on a think converging lens of focal length f. Briefly explain how the focal length of the lens will change,if red light is replaced with blue light.

How does the power of a convex lens vary,if the incident violet light is replaced by red light?
