283558 White light, with a uniform intensity, is perpendicularly incident on a water film of refractive index 1.33 and thickness \(320 \mathrm{~nm}\), that is suspended in air. At what wavelength is the light reflected by the film brightest to an observer?

1 \(459 \mathrm{~nm}\)
2 \(567 \mathrm{~nm}\)
3 \(623 \mathrm{~nm}\)
4 \(690 \mathrm{~nm}\)

283552 Fraunhofer lines are due to:

1 the diffraction effects in the atmosphere
2 the absorption of sun's radiation by the earth's atmosphere
3 the absorption of sun's radiation by the sun's atmosphere
4 the characteristic emission of sun's radiation

283479 A beam of natural light falls on a system of 5 Polaroid's, which are arranged in succession such that the pass axis of each Polaroid is turned through \(60^{\circ}\) with respect to the preceding one. The fraction of the incident light intensity that passes through the system is

1 \(\frac{1}{64}\)
2 \(\frac{1}{32}\)
3 \(\frac{1}{256}\)
4 \(\frac{1}{128}\)
5 \(\frac{1}{512}\)
