can we get interference using white light?

What is interference of light?

Estimating the following numbers should be interesting. The number tells you why our eye can never count photons, even in barely detetable light. The number of photons entering the pupil of our eye per second corresponding to the minimum intensity of white light that we humans can perceive (~10^-10 Wm^-2) . Take the area of the pupil to be about 0.4 cm^2 , and the average frequency of white light to be about 6 xx 10^14 Hz .

Describe an experiment to show that different color of white light can be recombined to from white light.

What is the effect on the interference fringes in a Young's double slit experiment due to each of the following oerations? The monochromatic source is replaced by a source of white light.

Compare the phenomenon of interference and diffraction of light.
