283462 A ray of light of intensity \(I\) is incident on a parallel glass slab at point \(A\) as shown in diagram. It undergoes partial reflection and refraction. At each reflection, \(25 \%\) of incident energy is reflected. The rays \(A B\) and \(A\) ' \(B\) ' undergo interference. The ratio of \(I_{\max }\) and \(I_{\min }\) is :

283463 An interference pattern the position of zeroth order maxima is \(4.8 \mathrm{~mm}\) from a certain point \(P\) on the screen. The fringe width is \(0.2 \mathrm{~mm}\). The position of second order maxima from point \(P\) is

283465 Two beams of light of intensity \(I_1\) and \(I_2\) interfere to give an interference pattern. If the ratio of maximum intensity to that of minimum intensity is \(\frac{25}{9}\), then \(\frac{I_1}{I_2}\) is
