In a Young's double slit experiment, the source is white light. One of the holes is covered by a red filter and another by a blue filter. In this case

Options

A. There shall be alternate interference patterns of red and blue
B. There shall be an interference pattern for red distinct from that for blue
C. There shall be no interference fringes
D. There shall be an interference pattern for red mixing with one for blue

Answer

C

Explanation

For the interference pattern to be formed on the screen, the sources should be coherent and emits lights of same frequency and wavelength. In a Young’s double-slit experiment, when one of the holes is covered by a red filter and another by a blue filter then only red and blue lights are present.
