The diffraction fringes obtained by a single slit are of

The central fringe of diffraction pattern obtained by single slit for white light will be

How will the diffraction pattern in a single slit be affected if (i) the width of the slit is increased?

In the diffraction pattern of a single slit aperture, the width of the central fringe compared to widths of te other fringes is-

A single slit diffraction pattern is obtained using a beam of red light. If the red light is replaced by the blue light, then the diffraction pattern

(a) Using Huygen's principle draw a diagram to whow propagation of a front originating from a monochrmatic source. (b) Desctibe diffraction of light due to a single slit. Explain formation of a pattern of fringes obtained on the screen and plot showing variation of intensity with angle theta in single slit diffraction.

In Fraunhoffer diffraction from a single slit, wave front incident on the slit is
