#3. Which of the following quantity is unitless ?
#4. An astronomical telescope has an angular magnification of magnitude 5 for distance objects. The separation between the objective and the eye-piece is 36 cm and the final image is formed at infinity. The focal length fo of the objective and fe of the eye-piece are
#5. An object is placed in front of a convex mirror at a distance of 50 cm. A plane mirror is introduced covering the lower half of the convex mirror.
