The parallel incident rays fall on the mirror’s surface and the rays reflect and meet at a certain point known as the focal point. A concave mirror’s shape is similar to a spoon. When we place this mirror too close to an object, we get a magnified and virtual image.

WebbA Concave Lens is a lens where it diverges a direct light beam from a source into a scaled-down, upright virtual image. It can create both the real and virtual images. Concave lenses have at least one surface curved inward. A concave lens is also diverging because it is shaped inward at the center and bulges outward over the edges, spreading ... Webb15 nov. 2024 · The concave mirror is the converging mirrors, due to the fact that when parallel incident rays fall on the surface of the mirror, the rays will reflect and meet at a particular point, i.e. focal point. Its shape is identical to a spoon. The reflecting surface of a concave mirror bent inward to focus, i.e. away from the light source.

WebbDefinition of Double Concave Lens. Double-Concave Lenses (DCV or Biconcave Lenses) are employed in beam expansion, image reduction, and light projection applications.
