Solution
In Young's double slit experiment, if one slit is covered with a red filter and the other with a blue filter, there will be no interference.
Here's why:
-
The principle of Young's double slit experiment is based on the interference of light waves, which requires the waves to be coherent. Coherence means the waves must maintain a constant phase difference, which is only possible if they are of the same wavelength (color).
-
When you place a red filter over one slit and a blue filter over the other, the light passing through the red filter will be red light (longer wavelength), and the light passing through the blue filter will be blue light (shorter wavelength).
-
Since red and blue light have different wavelengths, they cannot maintain a constant phase difference and are therefore not coherent.
-
Without coherence, the light waves cannot interfere to produce an interference pattern.
So, the result will be no interference.
