Superposition, Coherence & Intensity
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
Show answer and solution
Answer: (c)
- Interference needs coherent waves of the same frequency.
- Red light from one slit and blue light from the other have different frequencies, so they are not coherent.
- No sustained interference pattern forms, so the answer is (c).
