Sample questions
-
1.Consider the following statements in context with the sign conventions for spherical lens and choose the incorrect one I. All the distances are measured from the pole of the lens. II. The distances measured against the direction of incident light are taken as negative. III. The distances measured downward and perpendicular to the principal axis are taken as negative.
- a.Only II
- b.Only I
- c.III only
- d.All are incorrect
-
2.UV rays have wavelength ... that of IR rays.
- A.equal to
- B.smaller than
- C.larger than
- D.none of these
-
3.Which of the following procedures correctly demonstrates the composite character of white light as shown by Newton using prisms?
- A.Passing sunlight through a single prism to split it into colors, then using a second prism to recombine them into white light.
- B.Reflecting sunlight off a mirror to produce a spectrum of colors on a screen.
- C.Using a single prism to split sunlight into colors without further recombination.
- D.Shining sunlight through a convex lens to focus it into a single white spot.
-
4.State the correct condition when the lens has both its focal lengths equal.
- A.medium is same on either side of lens
- B.when refractive index is one
- C.medium is different on either side of lens
- D.All of the above
-
5.The linear magnification of a thin lens is given the symbol M. The following equation for M is used for lenses in cameras. M = f / (d - f) Where f is the focal length of the lens and d is the distance between the lens and an object. A lens has a focal length of 12 cm. (i) Use the equation to calculate M when the distance from an object to the lens is 14 cm. (ii) Use the equation to calculate M when the distance from an object to the lens is 11 cm.
