Important Questions for Practice



  1. Show that maximum intensity in interference pattern is four times the intensity due to each slit if amplitude of light emerging from slits is same.
  2. A person looking at a mesh of crossed wire is able to see the vertical wire more distinctly than the horizontal wire. Which defect he is suffering from? How can this defect be corrected?
  3. How is a wave front different from a ray? Draw the geometrical shape of the wave fronts when.
    (i) light diverges from a point source, (ii) light emerges out of convex lens when a point source is placed at
    its focus.
  4. Define diffraction. Deduce an expression for fringe width of the central maxima of the diffraction pattern, produced by single slit illuminated with monochromatic light source
  5. State the condition under which the phenomenon of diffraction of light takes place. Derive an expression for the width of the central maximum due to diffraction of light at a single slit. Also draw the intensity pattern with angular position.
Try These
  • A ray of light passes through an equilateral prism in such a manner that the angle of incidence is equal to angle of emergence and each of these angles is equal to 3/4 of angle of prism. Find angle of deviation.
  • Critical angle for a certain wavelength of light in glass is 30°. Calculate the polarizing angle and the angle of refraction in glass corresponding to this.
  • An object of length 2.5cm is placed at a distance of 1.5f from a concave mirror where f is the focal length of the mirror. The length of object is perpendicular to principal axis. Find the size of image. Is the image erect or inverted?
  • A radio can tune into any station of frequency band 7.5 MHz to 10 MHz. Find the corresponding wave length range.
  • Describe an astronomical telescope and derive an expression for its magnifying power using a labelled ray diagram.
