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,

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

Text Solution

Verified by Experts

The correct Answer is:
C
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. In this case due to filteration only red and blue lights are present. In YDSE monochromatic light is used for the formation of fringes on the screen Hence, in this case there shall be no interference fringes.
