WAVE OPTICS

283358 A parallel beam of monochromatic light of wavelength \(5625 \stackrel{\circ}{\AA}\) passes through a long slit of width \(0.25 \mathrm{~mm}\). The angular divergence in which most of the light is diffracted is:

1 \(4.5 \times 10^{-3}\) radian
2 \(2.25 \times 10^{-3}\) radian
3 \(4.5 \times 10^{-4}\) radian
4 \(2.25 \times 10^{-4}\) radian

283359 White light is used to illuminate two slits in Young's double slit experiment. The separation between the slits is \(b\) and the screen is at a distance \(d(>>b)\) from the slits. At a point on the screen directly in front of one of the slits, which wavelength are missing?

1 \(\frac{\mathrm{b}}{\mathrm{d}}, \frac{\mathrm{b}}{3 \mathrm{~d}}, \frac{\mathrm{b}}{5 \mathrm{~d}}\)
2 \(\frac{\mathrm{b}^2}{2 \mathrm{~d}}, \frac{\mathrm{b}^2}{4 \mathrm{~d}}, \frac{\mathrm{b}^2}{6 \mathrm{~d}}\)

283361 In a Young's double slit experiment, the two slits which are separated by \(1.2 \mathrm{~mm}\) are illuminated with a monochromatic light of wavelength 6000 angstrom. The interference pattern is observed on a screen placed at a distance of \(1 \mathrm{~m}\) from the slits. Find the number of bright fringes formed over \(1 \mathrm{~cm}\) width on the screen.
