Differbetween
Concave describes shapes that curve inward, like an hourglass. Convex describes shapes that curve outward, like a football (or a rugby ball).

What is the main difference between concave and convex mirror?
| Concave mirror | Convex mirror |
|---|---|
| It is also called a converging mirror. | It is also called a diverging mirror. |
| It has a real focus. | It has a virtual focus. |
| The magnification of a concave mirror can be greater, equal or less than 1. | The magnification of a convex mirror is always less than 1. |
What is difference between concave and convex mirror Class 7?
Question 1: What is the difference between concave and convex mirror in terms of type? Answer 1: Convex mirrors are diverging mirrors whereas concave mirrors are converging mirrors. ... Answer 2: Concave mirrors are used in headlights, searchlights and projectors as they give a magnified image of the objects.
What are the differences between the images formed by convex and concave lenses?
The focal length of a convex lens is positive, while that of a concave lens is negative. ... On the contrary, the image formed by the concave lens is erect, virtual and smaller, than the object. Due to the thicker centre of convex lenses, the objects are seen larger and closer.
What are the properties of concave and convex mirrors?
What are convex and concave mirrors? If the inner side of the spherical mirror is reflecting, it is called a concave mirror. If the outer side of the spherical mirror is reflecting, it is called a convex mirror. Concave mirrors can form inverted and real images and also virtual and erect images.
What are the examples of convex mirror?

| Concave mirror | Convex Mirror |

| The examples of concave mirrors are the mirrors used in automobile head lights, reflecting telescopes, torch lights, etc. | The examples of convex mirrors are the mirrors used as rear side mirrors of vehicles, optical instruments, calling bell, etc. |
Where do we use concave mirrors?
Uses Of Concave Mirror
- Shaving mirrors.
- Head mirrors.
- Ophthalmoscope.
- Astronomical telescopes.
- Headlights.
- Solar furnaces.
What type of image can a concave mirror produce?
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.
How concave and convex mirrors are formed?
Virtual images are always formed by convex mirrors and are formed by concave mirrors when the object is placed in front of F. ... 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 similarities between concave and convex lenses?
Similarities between lenses and 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 examples of concave lenses?
There are many examples of concave lenses in real-life applications.
- Binoculars and telescopes.
- Eye Glasses to correct nearsightedness.
- Cameras.
- Flashlights.
- Lasers (CD, DVD players for example).
What type of image is converted by convex lenses?
Convex (converging) lenses can form either real or virtual images (cases 1 and 2, respectively), whereas concave (diverging) lenses can form only virtual images (always case 3). Real images are always inverted, but they can be either larger or smaller than the object.
