Monochromatic light of wavelength 580 nm is incident on a slit of width 0.30 mm. The screen is 2m from the slit . The width of the central maximum is

Two fine slits are placed very close to each other and they are illuminated by a strong beam of light of wavelength 5900Å . Fringes are obtained at a distance of 0.3 m from the slits. The fringe width is found to be 5.9 xx 10^(-5)m . Calculate the distance between the slits.

Two parallel slits 0.6mm apart are illuminated by light source of wavelength 6000Å . The distance between two consecutive dark fringe on a screen 1m away from the slits is

Light of wavelength 6000 overset (@)(A) is incident normally on a slit . The first minimum in the diffraction pattern is observed to be at a distance of 6 mm from the central maximum on a screen , which is at a distance of 2 m from the slit . Calculate the width of the slit .

In the diffration due to single slit experiment, the aperture of the slit is 3 mm. If monochromatic light of wavelength 620 nm in incident normally on the slit, calculate the separation in between the first order minima and the 3^("rd") order maxima on one side of the screen. The distance between the slit and the screen is 1.5 m.

A screen is placed at a distance of 1m from a narrow slit. Light of wavelength 0.5 micron is fallilng normally on the slit. If the first minima of the diffraction pattern is situated at 5 m m from the central maximum, find the width of the slit.

A beam of monochromatic light of wavelength 500 nm falls on two parallel slits. The distance between the slits is 0.15 mm. Determine the width of the interference fringes in mm unit on a screen placed at a distance of 1.5 m from the plane of the slits.
