A parallel beam of monochromatic light falls normally on a single narrow slit. How does the angular width of the principal maxima in the resulting diffraction pattern depend on width of the slit?

A parallel beam of monochromatic light falls normally on a single narrow slit. How does the angular width of the central maximum in the resulting diffraction pattern depend on the wavelength of the incident light?

Light of wavelength 550nm is incident as parallel bea on a silt of width 0.1 mm.Find the linear width and the angular width of the principal maxima in the resulting diffraction pattern on a screen kept at a distance of 1.1 m from the slit.Which of these widths would not change,if the screen were moved to a distance of 2.2 m from the slit?

A parallel monochromatic beam of light is incident normally on a narrow slit.A diffraction pattern is formed on a screen placed perpendicular to the direction of the incident beam.At the first minimum of the diffraction pattern,the phase difference between the rays coming from the two edges of the slit is

A parallel beam of light of wavelength 500 nm (Nanometer) falls on a narrow slit and the resulting diffraction pattern is observed on a screen 1 metre away. It is observed that the first minimum is at a distance of 2.5 mm (milimetre) from the centre of the screen. Find the width of the slit.

If I_0 is the intensity of the principal maximum in the singel slit diffraction pattern,then what will be its intensity when the slit width is doubled?

Draw the diffraction pattern due to a single slit by a monochromatic light.

A slit of width d is placed in the path of the beam of wavelength lambda . The angular width of the principle maximum obtained is:

Discuss fully diffraction at a single slit and derive the relation for the linear width of central maximum.
