Three lights, red, violet and green are used successively in YDSE. Which one will have the maximum fringe width ?
Answer & explanation
Correct answer: option 1
\(\beta\) ∝ \(\lambda \)
Correct answer is Red, as it has maximum wavelength . Fringe width is directly proportional to the wavelength. So red has the maximum fringe width whereas Violet has minimum fringe width.
