Now hinge the mirrors using the adhesive tape at different angles, say 45º, 60º, 120º, 180º, etc. Place some object (say a candle) in between them. Note down the number of images of the object in each case. Finally, set the two mirrors parallel to each other. Find out how many images of a candle placed between them are formed.
