Question
If the monochromatic light shown in Fig. 35.5a were replaced by white light, would a two-slit interference pattern be seen on the screen? Explain.
Step-by-Step Solution
Verified Answer
No, instead of dark and bright fringes, some colored fringes will be observed.
1Step 1: Define the principle of superposition.
The necessary and essential condition for interference to take place is that the light rays should be monochromatic and coherent to each other.
2Step 2: Find if white light is replaced by monochromatic light, then will a two-slit interference pattern be seen on the screen or not.
The white light contains different colors and due to this instead of dark and bright fringes, we will get some colored fringes and then uniform illumination.
Hence, the pattern could not be visible in the case of white light.
