Question

Draw a ray diagram of the image of an object formed by a concave lens.

Hint:

Concave lenses are commonly used in spectacles to correct myopia (nearsightedness).

Answer 1

A concave lens always forms a virtual, erect, and diminished image irrespective of object placement. The image is formed between the lens and the focal point on the same side as the object. The ray diagram below illustrates this: \[ A[blue] --[:30] L --[:-30] B[blue] \]
