283161 In Young's double slit experiment instead of taking slits of equal widths, one slit is made twice as wide as the other. Then in the interference pattern,

1 the intensity of maxima decreases and that of minima decreases.
2 the intensities of both the maxima and minima increase.
3 the intensity of maxima decreases and the minima has zero intensity.
4 the intensity of maxima increases and the minima has zero intensity.

283162 In Young's double slit experiment, for wavelength \(\lambda_1\) the \(n^{\text {th }}\) bright fringe is obtained at a point \(P\) on the screen. Keeping the same setting, source of light is replaced by wavelength \(\lambda_2\) and now \((n+1)^{\text {th }}\) bright fringe is obtained at the same point \(P\) on the screen. The value of \(\mathbf{n}\) is

1 \(\frac{\lambda_1}{\lambda_1-\lambda_2}\)
2 \(\frac{\lambda_2}{\lambda_1-\lambda_2}\)
3 \(\frac{\lambda_1-\lambda_2}{\lambda_2}\)
4 \(\frac{\lambda_1-\lambda_2}{\lambda_1}\)
