The lens is the curved-shaped transparent glass piece that can be created through the use of plastic that used to do the refraction and focusing of light. The curved area of the lens defines about the quantity through which light gets bent and the direction of movement.
There are 2 main types of lens first one is the concave and the second one is the convex lens in the case of the convex lens the light rays meet ar single point or focus point while in the case of concave lens light rays diverge from the point. So let’s get started
Difference Between Concave and Convex Lens
- The structure of the concave lens is such that it has one side curve toward the inner side.
- Its behaviour is diverging which means that indicates that it changes the beams coming to it.
- This lens has edges thick than another surface. It used for the treatment of myopia that is a disease of short sight ness.
- The structure of this lens is opposite of the concave lense mean its inner side is thick the outer side or edges.
- Ray of light after passing through it merge at a single point called the focal point.
- It also called converging lens
- It used in cameras
The main types of convex lens are
- Plano-convex lens
- Double convex lens
- concave convex lens
- The lenses have 2 main types according to surface design. Id both sides of the lens is convex called biconvex lenses.
- If there is the same radius at both sides then it called eqviconvax. Two concave surfaces called biconvex.
- Is one side is flat called the plane concave lens. In case biconvex lens ray of light moving through lens spot at behind of lense.
What is Magnification
- The ratio between the size of the image to the size of object called magnification. It is denoted with M.
- For real images, its value is denoted with negative and for positive it denoted with positive M.
Magnification= Image hight/object hieght
What is Optical Aberration
- The aberration is feature of the optical system the lens has the property to separate the light at a given area. Due to aberration image created through the lens is dim or not clear
- For imaging, the results is aberration if the light does not fall at a single point after moving through the system
That is all about the Difference Between the Concave and Convex Lens if you have any further quey ask in commetns. thanks for reading have a good day
