Coherent Sources of Light and interference of Light Constructive, Distractive
WAVE OPTICS

283180 Interference fringes are obtained in a Young's double slit experiment using beam of light consisting two wavelengths \(500 \mathrm{~nm}\) and 600 \(\mathrm{nm}\). Bright fringes due to both wavelengths coincide at \(2.5 \mathrm{~mm}\) from the central maximum. If the separation between the slits is \(3 \mathrm{~mm}\), then the distance between the screen and plane of the slits is

1 \(1.2 \mathrm{~m}\)
2 \(2.8 \mathrm{~m}\)
3 \(2.5 \mathrm{~m}\)
4 \(3.2 \mathrm{~m}\)
WAVE OPTICS

283181 In an experiment, light passing through two slits separated by a distance of \(0.3 \mathrm{~mm}\) is projected on to a screen placed at \(1 \mathrm{~m}\) from the plane of slits. It is observed that the distance between the central fringe and the adjacent bright fringe is \(1.9 \mathrm{~mm}\). The wavelength of light in \(\mathrm{nm}\) is

WAVE OPTICS

283182 Calculated the minimum thickness of a soap film \((\mu=1.33)\) that results in constructive interference in reflected light, if the film is illuminated with light whose wavelength in free space is \(532 \mathrm{~nm}\).

1 \(113 \mathrm{~nm}\)
2 \(100 \mathrm{~nm}\)

283183 In Young's double slit experiment, the intensity of light coming from one of the slits is double the intensity from the other slit.
The ratio of the maximum intensity to the minimum intensity in the interference fringe pattern observed is

WAVE OPTICS

283185 Two coherent sources of equal intensities produce maximum intensity of 100 units at a point. If the intensity of one of the sources is reduced by \(50 \%\) by reducing its width, then the intensity of light at the same will be units.
