Question

State any two precautions you took when performing this experiment. EXPERIMENT 17: LINEAR MAGNIFICATION APPARATUS: Ray box, convex lens, screen, optical bench, meter rule, 2 lens holder. Fig. 4 An illuminated object (crosswire) from a ray box of fixed distance (ho) is provided. Measure and record (ho), keeping (ho) constant throughout, place the object at \( \mathrm{U}=20.0 \mathrm{~cm} \) from a convex lens to produce an image on the screen of distance \( V \). Record \( V \) and also measure the size (hi) of the image. Evaluatem \( = \) hih \( _{0} . \). Repeat the experiment for \( \mathrm{U}=25,30,35,40 \mathrm{~cm} \) and in each case, determine \( \mathrm{h} 1, \mathrm{~V} \) and m .

          State any two precautions you took when performing this experiment.
