Q1. By using the converging lens of focal length f = 10cm, we wish for an object to appear on a screen twice bigger than its original size. Determine where is the object to be situated in front of the screen (or real image)?

Q2. We wish for an object to appear two times larger by using a concave mirror of radius of curvature R = 50cm

a) If the object is positioned between the centre and the focal point, then where is the object to be positioned if it is real, inverted and magnified?

b) If the object is positioned between the focal point and the mirror surface then where is the object to be positioned if it is virtual, upright and magnified?
