In Young\'s double slit experiment the source is white light. One slit is covered with red filter and the other with blhe filter. There shal be

It seems like you didn't finish your question. However, I can tell you what would happen in Young's double slit experiment if one slit is covered with a red filter and the other with a blue filter.

1. Young's double slit experiment is a demonstration that light and other forms of electromagnetic radiation can exhibit both wave-like and particle-like properties. It involves shining light through two closely spaced slits and observing the interference pattern on a screen.

2. If you cover one slit with a red filter and the other with a blue filter, the light passing through each slit will be of that color. The red filter will only allow red (long-wavelength) light to pass through, and the blue filter will only allow blue (short-wavelength) light to pass through.

3. On the screen, you would see two overlapping interference patterns, one for red light and one for blue light. This is because each color of light has a different wavelength, and the pattern of light and dark fringes (bright and dark spots) in an interference pattern depends on the wavelength of the light.

4. The red light pattern would have wider spacing between the fringes, because red light has a longer wavelength than blue light. The blue light pattern would have narrower spacing between the fringes, because blue light has a shorter wavelength.

5. Where the red and blue light overlap, you would see magenta light. This is because our eyes perceive light that is both red and blue at the same time as being magenta.

6. If the filters are perfect, meaning they only allow their respective colors to pass through and completely block all other colors, then there would be no white light in the interference pattern. If the filters are not perfect and allow some other colors to pass through, then you might see some white or other colors in the interference pattern.
