283389 Two sources give interference pattern which is observed on a screen, placed at a distance \(D\) from the sources. The fringe width is given as 2 W. If the distance of sources from the screen is doubled, then the fringe width will

1 become \(\mathrm{W} / 2\)
2 remains the same
3 become \(\mathrm{W}\)
4 become \(4 \mathrm{~W}\)

283392 In a double slit experiment, \(5^{\text {th }}\) dark fringe is formed opposite to one of the slits the wavelength of light is

1 \(\frac{d^2}{6 \mathrm{D}}\)
2 \(\frac{d^2}{5 D}\)
3 \(\frac{\mathrm{d}^2}{15 \mathrm{D}}\)
4 \(\frac{d^2}{9 \mathrm{D}}\)

283393 In Young's double slit experiment, the spacing between the slits is \(d\) and wavelength of light used is \(6000 \AA\). If the angular width of a fringe formed on a distance screen is \(1^{\circ}\), then value of \(d\) is

1 \(1 \mathrm{~mm}\)
2 \(0.05 \mathrm{~mm}\)
3 \(0.03 \mathrm{~mm}\)
4 \(0.01 \mathrm{~mm}\)

283394 Four light sources produce the following four waves:
(i) \(\mathrm{y}_1=\mathrm{a} \sin \left(\omega \mathrm{t}+\phi_1\right)\)
(ii) \(y_2=a \sin 2 \omega t\)
(iii) \(\mathbf{y}_3=\mathbf{a} \sin \left(\omega t+\phi_2\right)\)
(iv) \(\mathbf{y}_4=a \sin (3 \omega t+\phi)\)
Superposition of which two waves give rise to interference?

1 (i) and (ii)
2 (ii) and (iii)
3 (i) and (iii)
