  • Question 1
    4 / -1

    Shown in the figure here is a convergent lens placed inside a cell filled with a liquid. The lens has focal length +20 cm when in air and its material has refractive index 1.50. If the liquid has refractive index1.60, the focal length of the system is

  • Question 2
    4 / -1

    An isosceles prism of angle 120° has a refractive index of 1.44. Two parallel monochromatic rays enter the prism parallel to each other in air as shown. The rays emerging from the opposite faces

  • Question 3
    4 / -1

    A ray of light is incident on the hypotenuse of a right-angled prism after travelling parallel to the base inside the prism. Ifµ is the refractive index of thematerial of the prism, the maximum value of the base angle for which light is totally reflected from the hypotenuse is

  • Question 4
    4 / -1

    The refractive index of the material of the prism and liquid are 1.56 and 1.32 respectively. What will be the value of 9 for the following refraction?

  • Question 5
    4 / -1

    A spherical surface of radius of curvature R separates air (refractive index 1.0) from glass (refractive index 1.5). The centre of curvature is in the glass. A point object P placed in air is found to have a real image Q in the glass. The line PQ cuts the surface at a point O, and PO = OQ. The distance PO is equal to

  • Question 6
    4 / -1

    A plano-convex lens when silvered in the plane side behaves like a concave mirror of focal length 30cm. However, when silvered on the convex side it behaves like a concave mirror of focal length 10 cm. Then the refractive index of its material will be

  • Question 7
    4 / -1

    A ray of light travels from an optically denser to rarer medium. The critical angle for the two media is C. The maximum possible deviation of the ray will be

  • Question 8
    4 / -1

    An astronaut is looking down on earth\'s surface from a space shuttle at an altitude of 400 km. Assuming that the astronaut\'s pupil diameter is 5 mm and the wavelength of visible light is 500 nm. The astronaut will be able to resolve linear object of the size of about

  • Question 9
    4 / -1

    A small source of light is to be suspended directly above the centre of a circular table of radius R. What should be the height of the light source above the table so that the intensity of light is maximum at the edges of the table compared to any other height of the source

  • Question 10
    4 / -1

    A light source is located at P1 as shown in the figure. All sides of the polygon are equal. The intensity of illumination at P2 is I0. What will be the intensity of illumination at P3
