1. a) i) State two differences between real and virtual images.
ii) Explain with the aid of a diagram how a thick plane mirror forms multiple images.
b) A concave mirror forms a real image which is three times the linear size of the object. When the object is
displaced through a distance y, the real image formed is four times the linear size of object. If the distance between
the two image positions is 20.0cm, find the
