Physics

Questions

  • HardTwo statements about interference of light from two narrow slits, lit by the same coherent monochromatic source, are given below. Statement I: With the screen where it is, moving the two slits closer together makes the fringes on the screen narrower. Statement II: At the dark fringes the energy of the two waves is destroyed, so the total energy reaching the screen is less than the sum of the two separate beams.
  • AdvancedSix statements about wavefronts and interference are given below. (i) Light from two sodium lamps gives a steady interference pattern. (ii) Coherent waves of intensity I₀ each give 4I₀ in phase. (iii) A point source at a lens focus gives plane wavefronts. (iv) A small part of a distant spherical wavefront is nearly plane. (v) A wavefront joins points that oscillate with a phase difference of π. (vi) A reflected plane wave obeys the law of reflection. How many of the statements above are correct?

  • HardUnpolarised light of intensity I₀ falls on three polaroids P1, P2 and P3 in a row, all facing the beam as the figure shows. A polaroid passes only light polarised along its transmission axis. The transmission axes of P1, P2 and P3 make angles of 0°, 30° and 90° with the vertical. What is the intensity of the light that comes out of P3?
  • MediumA toolbox of mass 0.70 kg sits on a trolley of mass 2.1 kg. The trolley rolls without friction and is joined to a fixed post by a spring of 135 N/m. The friction coefficient between toolbox and trolley is 0.32. The trolley is pulled aside and released. How far can it be pulled before the toolbox slides?
  • AdvancedAssertion (A): A narrow beam of light of a single colour passes from air into a glass block. The frequency of the light in the glass is the same as its frequency in air. Reason (R): The speed of the light in the glass is smaller than its speed in air.

    Questions

    • AdvancedExcess silver powder is shaken at 298 K with a solution of iron(III) perchlorate, [Fe³⁺] = 0.100 mol L⁻¹, in dilute perchloric acid. The acid stops the iron(III) ions from hydrolysing, and perchlorate does not react. The reaction is Ag(s) + Fe³⁺(aq) ⇌ Ag⁺(aq) + Fe²⁺(aq). At the start there are no Ag⁺ or Fe²⁺ ions. Take E°(Fe³⁺/Fe²⁺) = 0.77 V, E°(Ag⁺/Ag) = 0.80 V and 2.303RT/F = 0.059 V. Treat the solution as ideal, and take its volume as fixed. The mixture is left until it reaches equilibrium.
