List of top Physics Questions on Diffraction asked in JEE Main

A slit of width \(a\) is illuminated by light of wavelength \(\lambda\). The linear separation between 1st and 3rd minima in the diffraction pattern produced on a screen placed at a distance \(D\) from the slit system is ______.

In a YDSE setup, the slits are separated by 1.5 mm and the distance between the slits and the screen is 2 m. On using light of wavelength 400 nm, it is observed that 20 maxima of double slit experiment lie inside the central maxima of single slit diffraction. The width of each slit is μm.

A microwave of wavelength 2.0 cm falls normally on a slit of width 4.0 cm. The angular spread of the central maxima of the diffraction pattern obtained on a screen 1.5 m away from the slit, will be:
