In a young's double slit experiment light of wavelength is used. is the nearest point from the central maximum where intensity is of the maximum intensity. What percentage of the maximum intensity is observed at point if light is replaced by the wavelength ?
View answer and explanation
Correct option: B
Option B (75%) is correct because when the wavelength changes, the phase difference at point P changes, leading to a different intensity which is calculated to be 75% of the maximum intensity.
