(a) A lens forms an image between the object and the lens. Name the lens.(b) Draw a ray diagram to show the formation of such an image.(c) State one characteristic of the image.

(a) The lens that forms an image between the object and the lens is a concave lens, also known as a diverging lens.

(b) To draw a ray diagram for a concave lens:

1. Draw a horizontal line to represent the principal axis.
2. Draw a vertical line in the middle of the principal axis to represent the lens.
3. Draw an arrow on the left side of the lens to represent the object.
4. Draw a line from the top of the object arrow, parallel to the principal axis, towards the lens. Once it hits the lens, it should diverge away from the principal axis.
5. Draw another line from the top of the object arrow, through the center of the lens. This line will continue straight without bending.
6. The point where these two lines appear to meet on the left side of the lens is where the image is formed.

(c) One characteristic of the image formed by a concave lens is that it is always virtual, upright, and reduced in size.
