Explain why the maxima at `theta=(n+1/2)lambda/a` become weaker and weaker with increasing n
Describe briefly how a diffraction pattern is obtained on a screen due to a single narrow slit illuminated by a monochromatic source of light. Hence obtain the conditions for the angular width of secondary maxima and secondary minima.
In Fraunhofer diffraction, how is the angular width of the central bright fringe affected when slit separation is increased?
Two wavelengths of sodium light 590 nm and 596 nm are used, in turn to study the diffraction taking place at a single slit of aperture 2 × 10−4m. The distance between the slit and the screen is 1.5 m. Calculate the separation between the positions of the first maxima of the diffraction pattern obtained in the two cases.
Two wavelengths of sodium light 590 nm and 596 nm are used, in turn, to study the diffraction taking place due to a single slit of aperture 1 × 10−4 m. The distance between the slit and the screen is 1.8 m. Calculate the separation between the positions of the first maxima of the diffraction pattern obtained in the two cases.
What should be the order of obstacle or aperture for diffraction of light?
Direction of the first secondary maximum in the Fraunhoffer diffraction pattern at a single slit is given by (a is the width of the slit):
Write two points of difference between an interference pattern and a diffraction pattern.
How can you differentiate whether a pattern is produced by a single slit or double slit?
In a diffraction pattern due to a single slit, how will the angular width of the central maximum change, if the slit width is decreased?
