Concave Lens: Definition, Properties
What are examples of concave lenses? On this occasion About the knowledge.co.id will discuss what it is Concave Lens and other elements about it. Let's look at the discussion together in the article below to better understand it.
Concave Lens: Definition, Properties, Formulas, Formation, Characteristics, Types and Benefits
The use of a concave lens in everyday life is no less significant than a convex lens help people who suffer from nearsightedness or myopia can be normalized again with the help of lenses sunken. A concave lens is a device that usually has a glass or plastic circle so that it can act as an index respiratory tract and acts as a magnifying glass and can also create a reflection of light from light reflection.
Definition of Concave Lens
A concave lens is a lens that is thinner in the middle than thicker at the edges. Concave lenses are generally circular in shape, although there are also concave lenses that are not circular in shape. A concave lens, like a convex lens, is usually made of glass or plastic so that the lens has a higher refractive index than air. A concave lens has the property of scattering light, so it is called a diverging lens. The identity of a concave lens itself can be easily seen from its shape, which has a thick identity on the edges and thin in the middle.
Light passing through a concave lens is bent toward the edge of the lens or away from the lens axis. Parallel incoming light is applied to a concave lens, the rays will spread as if they came from one point, namely the Focal Point. The focal point of a concave lens is located on the same side as the incident light so that the focal point of a concave lens has virtual or virtual properties and has a negative value.
The nature of the image of a concave lens
Following are some of the characteristics of the image of a concave lens, including:
- A concave lens has the character of scattering or emitting rays that arrive at it (divergent) so it is called a negative lens.
- A concave lens has 2 virtual focal points and is equidistant from the optical center point.
Concave Lens Formula
As with a convex lens, the formula for a concave lens applies:
Explanation:
- S' = image distance
- S'= (+) positive, real image
- S'= (–) negative, virtual image
- S = object distance
- F = Point distance a[i, negative value
The magnification (m) formula is:
Explanation :
- h'= (–) negative, the image is inverted
- h'= (+) positive, the image is upright
- m= (+) positive, image is upright
- m= (–) negative, inverted image
Image Formation on a Concave Lens
After studying what we have said above, we will also share reviews to observe the process of making shadows in their formulation. To determine the shadows, it takes 2 of the 3 lights that are in the process by making it through the problem on this basis. Objects placed between f and 2f are under construction and can be encountered at predefined steps.
Characteristics of a concave lens
A concave lens scatters light, so it is also called a diverging lens. The characteristics of a concave lens can be seen from its shape, which is thick at the edges and thin in the middle.
Rays passing through a concave lens will be bent towards the edge of the lens or avoid the lens axis. Parallel incoming light is applied to a concave lens, the light will spread as if it comes from one point, namely the Focal Point. The focal point of a concave lens is located on the same side as the incident light so that the focal point of a concave lens has a virtual or virtual character and has a negative value.
Concave Lens Type
There are also types of concave lenses, namely: double concave, flat concave and concave meniscus. The shape of a concave lens include:
- Biconcave or concave
- Planconcave or concave - flat
- Convex - concave or concave - convex
Benefits and Use of Concave Lenses
The main use of concave lenses is often found in people with nearsightedness as glasses so they can see things like normal human eyes. Not only glasses for people with nearsightedness, these lenses are also used in earth binoculars so that the oculars of the binoculars are short.
Thus the review from About the knowledge.co.id about Example of a concave lens, hopefully can add to your insight and knowledge. Thank you for visiting and don't forget to read other articles.
