Monochromatic coherent light with a wavelength of 632.8nm is incident on a double slit system with a slit separation of 0.15mm. What is the separation between the third bright spot from the center and the seventh bright spot from the center?
Distance between slit and screen (L) is not given. Put L in m then the separation between 4th and 7th bright spot will be in cm ie ( 1.69L cm).
If you have any doubt, feel free to ask in the comments.
