Difference Between Concave And Convex Mirror

Difference Between Concave And Convex Mirror

the Major Difference Between Concave And Convex Mirror is that the spherical mirror reflecting from the inner side is called a concave mirror while the spherical mirror with outside reflection is said to be a convex mirror. the concave mirror is also known as a converging mirror while the convex is diverging.

In this article you’ll learn:

  • What is the difference between concave and convex?
  • What is the use of convex and concave mirrors?
  • Where are concave and convex mirrors used?
  • What is a concave and convex shape?
  • Lots more…!

Let’s Get Started…!

Difference between Concave and Convex Mirror.

  1. A concave mirror is a spherical mirror with an inwardly curved reflection surface, whereas a convex mirror is a spherical mirror with an outwardly bulged reflecting surface.
  2. A concave mirror has a converging character and is so-referred to as a converging mirror, whereas a convex mirror has a diverging nature and is thus referred to as a diverging mirror.
  3. The concave mirror’s focus and center of curvature are located in front of the mirror, whereas the convex mirror is located on the backside.
  4. The focal length of the concave mirror is negative because the focus is on the front side that is distance is measured against the direction of light, but the focal length of the convex mirror is positive because the focus is on the backside that is distance is measured in the direction of light.
  5. On a concave mirror, image projection on the screen is possible, however on a convex mirror; image projection on the screen is not possible.
  6. A concave mirror’s magnification might be less than, equal to, or greater than 1. A convex mirror, on the other hand, has a value of magnification that is less than 1.
  7. A concave mirror creates an image that is often larger than the actual image, resulting in a magnified image. A convex mirror, on the other hand, provides an image that is generally smaller than the actual picture, giving the impression that the image is shrunk.

Differentiate between concave and convex mirror

The difference between concave mirror and convex mirror is listed below in tabular form:

ComparisonConcave mirrorConvex mirror
AppearanceA concave mirror is created when the outer surface of a spherical mirror is painted.A convex mirror has the inside surface of a spherical mirror painted.
Also calledConverging mirrorDiverging mirror
DesignA concave mirror is either spherical or hollowed out. Concave refers to the shape of a circle’s inside.A convex mirror is a curved, round mirror. Convex refers to the shape of a circle’s outside.
Reflecting surfaceHere, only the inner surface reflexes.Here, only the outer surface reflexes.
Focal lengthThe focal length is negativeThe focal length is positive.
Nature of imageReal and virtual.Only virtual.
UseThey give a magnified image of the objects and are used in reflecting telescopes, shaving mirrors, torch lights, and other similar devices.Convex mirrors are utilized in vehicles as a side or rearview mirror because they cover a larger region of vision.

The above table shows distinguish between concave and convex mirrors or concave and convex mirror difference.

What is a Concave Mirror?

concave mirrors and convex mirrors both belong to optical physics or optics (a branch of physics). Many students ask about the Difference Between Concave And Convex Mirror. so in this comprehensive guide, you’ll learn the answer to this query in detail.

to know the difference between these both, let’s try to discover first what is the mean of phenomenon concave and convex.

When we talk about concave, it merely means rounded or hollowed shape just like the interior of a shape or circle. So a concave mirror means mirror has a round or hollow shape.  It is also known as a converging mirror.

in structure, the concave mirror has a coating outside of the spherical surface and the reflecting surface of the image always falls on the same side of the mirror with the center of curvature. the position of focus lies in front of the concave mirror because the focal length is positive.

What is a Curved Mirror?

A mirror with a curved reflecting surface is known as a curved mirror. Convex (bulging outward) or concave (bulging inward) surfaces are possible. The surfaces of most curved mirrors are formed like a section of a sphere.

What is a Convex Mirror?

What is a Convex Mirror?

Convex mirrors are a type of diverging mirror. In these, the incident ray that emerges from the same point reflects off and moves in a different direction than before. As a result, the light rays do not intersect on the mirror’s object side and create the virtual image of the real object. You could say that it’s kind of like a spherical mirror in which the reflective surface curves outwards.

It will be able to create a virtual image after it reflects from the mirror; when you look through this reflection, all of the lights align at one point and form an accurate representation. Moreover, as they are erect, diminished, and concern objects in front of them — they are very similar to real mirrors.

FAQs about Concave And Convex Mirror

Question 1: What is the difference between concave and convex mirrors in terms of type?

Answer 1: Convex mirrors are diverging mirrors whereas concave mirrors are converging mirrors.

Question 2: Which mirror is used in headlights, searchlights and projectors?

Answer 2: Concave mirrors are used in headlights, searchlights and projectors as they give a magnified image of the objects.

Question 3: What is the difference between concave and convex mirrors in terms of physical appearance?

Answer: A concave mirror is formed by painting the outside surface of a spherical mirror, whereas a convex mirror is formed by painting the interior surface of a spherical mirror.

Question 4. What is the difference between concave and convex mirrors in terms of focus length?

Answer: The focal length of a concave mirror is positive because the focus is on the front side, whereas the focal length of a convex mirror is negative because the focus is on the backside.

Question 5. Can you tell the difference between concave and convex mirrors without touching them?

Answer: When you place an object in front of a concave mirror, an enlarged image of the object is generated when it is maintained near to the mirror, and an inverted picture of the object is formed when it is kept at a distance from the mirror. A convex mirror always creates a tiny, erect picture of the thing.

Question 6. Write examples of concave and convex mirrors.

Answer: Concave mirrors can be found in torch lights and automotive headlights. Convex mirrors include magnifying glasses and telescopes.

Question 7. Is centre of curvature component of a mirror?

Answer: The centre of curvature is not a component of the mirror, but rather exists outside of it. Concave and convex mirrors may be made from a single spherical glass by splitting it and polishing both pieces in opposite directions.
