Plano Convex Lens
Concavo Convex Lens
- Concave Lens:
If the lens is thinner in the center and thicker at the edges then it is known as a concave lens. It is a diverging lens.

It is for this reason that special training systems are currently being created that allow students to study in absentia. In this regard, distance education is in the first place in all respects, because information technology allows you to receive all the necessary material, as well as assignments and assessments remotely. Such a solution allows you to combine study and work in the absence of any extra costs for student days. In addition, even those people who live far from the educational institution itself, not to mention remoteness from the city, will be able to receive education in a distance mode.
