Question

Why does a concave lens make things look smaller?

Answer 1

Concave lens:

• Lenses that are thicker around their edges are concave lenses.
• A concave lens always forms virtual, erect, and diminished images.
• The concave lens is used in a variety of applications, including telescopes, cameras, lasers, glasses, binoculars, and so on.
• . The concave lens diverges or bends the refracted rays outwards because of its shape.
• These rays never meet to form the image.
• Therefore the images formed are virtual and small as shown below.
