Please help, I have also put on my recent tries. What have I done wrong?

In the four diagrams below, the solid arrow represents the object and the dashed arrow the image. The rectangle shows the position of an SINGLE OPTICAL ELEMENT. Match each diagram with the appropriate optical element. Plane Mirror Concave Mirror Diverging Lens Converging Lens First, is it a Lens or a Mirror? For a SINGLE ELEMENT, a Real image (RI) is always inverted, a Virtual image is always upright. Submit Answer Incorrect. Tries 3/5 Previous Tries

Explanation / Answer

a] For the first case, the image is on the other side and it is of a different size than the object. Thus, the optical element cannot be a plane mirror. The optical element is a concave mirror.

b] Here, the size of the image is identical and at the same distance. Thus, the optical element is a plane mirror.

c] The image is inverted and smaller in size. Therefore, the optical element is a converging lens.

d] The image is virtual, upright and smaller in size. Therefore, the optical element is a concave lens.
