diverging lens मीनिंग इन हिंदी

Converging lenses have positive optical power, while diverging lenses have negative power.
The distance found is the ( negative ) focal length of the diverging lens.
The focal length " f " is positive for converging lenses, and negative for diverging lenses.
Light from a laser is expanded by a diverging lens ( not shown ), then is collimated into a parallel beam.
A point source of monochromatic light is expanded by a diverging lens ( not shown ), then is collimated into a parallel beam.
*Whenever we look through a diverging lens ( one that is thicker at the edges than the middle ) or into a convex mirror, we see a virtual image.
Aside from reflection off solid surfaces, the 1 / r?law can be modified by temperature gradients above the ground, which can act as a converging or diverging lens.
Telephoto is designated because the longer focal length supplied by the negative diverging lens is longer than the overall lens assembly ( the negative diverging lens acting as the " telephoto group " ).
Telephoto is designated because the longer focal length supplied by the negative diverging lens is longer than the overall lens assembly ( the negative diverging lens acting as the " telephoto group " ).
With diverging lenses, incoming parallel rays diverge after going through the lens, in such a way that they seem to have originated at a spot one focal length in front of the lens.
