What are the characteristics of concave and convex mirror images?
A concave mirror has a reflective surface that is curved inward and away from the light source. Concave mirrors reflect light inward to one focal point. Unlike convex mirrors, the image formed by a concave mirror shows different image types depending on the distance between the object and the mirror.
What are the characteristics of image formed by a concave mirror?
Concave mirrors can produce both real and virtual images; they can be upright (if virtual) or inverted (if real); they can be behind the mirror (if virtual) or in front of the mirror (if real); they can also be enlarged, reduced, or the same size as object.
What are the characteristics of concave and convex?
In the Concave mirror, the outer side of the spherical mirror will be reflecting. In the Convex mirror, the inner side of the spherical mirror will be reflecting. A concave mirror will form a virtual or real image. A convex mirror will only form erect and virtual images.
What are the properties of image formed on concave and convex mirror based on where the object is placed?
When the object is placed anywhere between the principal focus and the pole of a concave mirror, we get an enlarged, virtual and erect image formed behind the mirror. Properties of image: Enlarged, Virtual and erect.
What are the similarities between concave and convex mirrors?
A convex lens acts a lot like a concave mirror. Both converge parallel rays to a focal point, have positive focal lengths, and form images with similar characteristics. A concave lens acts a lot like a convex mirror.
What are the characteristics of convex lens?
The convex lens is a lens that converges rays of light that convey parallel to its principal axis (i.e. converges the incident rays towards the principal axis) which is relatively thick across the middle and thin at the lower and upper edges. The edges are curved outward rather than inward.
What type of image is formed by concave and convex mirrors?
How can a plane mirror, concave mirror, and/or convex mirror be used to produce an upright image? Plane mirrors and convex mirrors will always produce an upright image. A concave mirror will only produce an upright image if the object is located in front of the focal point.
What are the characteristics of concave lens?
A concave lens is a lens that possesses at least one surface that curves inwards. It is a diverging lens, meaning that it spreads out light rays that have been refracted through it. A concave lens is thinner at its centre than at its edges, and is used to correct short-sightedness (myopia).
What is difference between concave and convex lens?
A convex lens is thicker at the centre and thinner at the edges. A concave lens is thicker at the edges and thinner at the centre. Due to the converging rays, it is called a converging lens.
What type of image is formed by concave and convex lens?
So, lenses formed by binding two spherical surfaces bulging outward are known as convex lenses while the lenses formed by binding two spherical surfaces such that they are curved inward are known as concave lenses….Image size.

How do you know if a shape is concave or convex?
The difference between convex and concave polygons lies in the measures of their angles. For a polygon to be convex, all of its interior angles must be less than 180 degrees. Otherwise, the polygon is concave.
What are convex and concave mirrors?
A curved mirror is a mirror with a curved reflecting surface. The surface may be either convex (bulging outward) or concave (recessed inward). Most curved mirrors have surfaces that are shaped like part of a sphere, but other shapes are sometimes used in optical devices.
