1.
A parallel beam of light of intensity \(I_0\) is incident on a coated glass plate. If \(25\%\) of the incident light is reflected from the upper surface and \(50\%\) of light is reflected from the lower surface of the glass plate, the ratio of maximum to minimum intensity in the interference region of the reflected light is- $\left(\frac{\frac{1}{2} + \sqrt{\frac{3}{8}}}{\frac{1}{2}- \sqrt{\frac{3}{8}}}\right)^{2} $
\(\left(\frac{\frac{1}{4} + \sqrt{\frac{3}{8}}}{\frac{1}{2}- \sqrt{\frac{3}{8}}}\right)^{2}\)
- $\frac{5}{8}$
- $\frac{8}{5}$

A wire of length \(L\) and cross-sectional area \(A\) has a Young's modulus \(Y\). If the wire is stretched by a force \(F\), the elongation produced in the wire is:- \( \frac{F}{A \cdot Y} \)
- \( \frac{F \cdot L}{A \cdot Y} \)
- \( \frac{A \cdot Y}{F} \)
- \( \frac{L}{A \cdot Y} \)

A wire of cross-sectional area \( 10^{-6} \, m^2 \) is elongated by \( 0.1 \% \) when the tension in it is \( 1000 \, N \). The Young's modulus of the material of the wire is (Assume radius of the wire is constant)?- \( 10^{11} \, Nm^{-2} \)
- \( 10^{12} \, Nm^{-2} \)
- \( 10^{10} \, Nm^{-2} \)
\( 10^{9} \, Nm^{-2} \)

- \( \frac{I}{3} \)
- \( \frac{2I}{3} \)
