The focal length is positive for concave mirrors and negative for convex mirrors. A concave mirror can form different image characteristics depending on the position of the object. If the object is beyond the center of curvature, the image formed is real (in front of the mirror), inverted, ...
The lens maker’s formula involves the focal length, refractive index of the material of the lens and the radius of curvature of the two surfaces of the lens. This formula is derived from the refraction of light on the two spherical surfaces of a lens. In Fig. refraction of light at the...
Additionally, the focal lengths of a convex lens and convex mirror differ in that the focal length of a convex lens is positive, while the focal length of a convex mirror is negative. The image formed by a convex lens can be either real or virtual, while the image formed by a convex ...
There are several important properties of concave mirrors that dictate the images formed. The most important characteristics are the focal point, the focal length, the center of curvature and the radius of curvature. All these properties are shown on the following diagram. Diagram showing the import...
known. After knowing the focal length of the lens the image formed by this lens at different object distances can be found by using the "thin lens formula" The lens-makers formula is actually a more general form of the lens formula. It can be applied to meniscus lens. ...
In addition there is a convergent lens and a convergent meniscus lens which have their concave sides facing towards the image. The claim also gives mathematical formula for determining the curvature of the lenses depending on their position in the lens system and the focal length of the system....
Power of a Lens The ability of a lens to bend the light falling on it is called the power of a lens. Since the lens of shorter focal length will bend the light rays more will have more power. A convex lens converges the light rays towards the principal axis whereas a concave lens ...

What are the two types of thin lenses? The two types of thin lenses are converging and diverging lenses. A converging, or convex, lens allows light to refract and meet at a single point. A diverging, or concave lens, causes parallel light rays to spread out and diverge.Lens...
