List of top Physics Questions on Diffraction asked in CUET (UG)

Angular width of central maxima increases when:

A slit of width \(e\) is illuminated by light of wavelength \(\lambda\). What should be the value of \(e\) to obtain the first maximum at an angle of diffraction \(\frac{\pi}{3}\)?

A parallel beam of light of wavelength 500 nm is incident normally on a slit of width d. If the distance between slit and screen is 0.6 m and distance of second order minimum from the centre of the screen is 6.0 mm, What is the width of the slit?
