Differentiate between concave mirrors and convex mirrors.
Answers
Answer:
There are many differences between concave and convex mirrors and some of them are as follows.
- CONCAVE MIRROR
If inner side of spherical mirror is reflecting, it is called as concave mirror.
- IMAGE
Concave mirrors form real and inverted images.
- NATURE
The images formed by the concave mirrors are magnified in nature.
- SIZE
The object in the image formed by the concave mirror look bigger than the original size of the object.
- POSITION
Concave mirrors form real and inverted images except when the object is between pole and focus.
- EXAMPLES
The examples of concave mirrors are the mirrors used in automobile head lights, reflecting telescopes, torch lights, etc.
- USAGE
Concave mirror is used in the solar furnace, the sun rays are focused at a point by the concave mirror.The concentrated beam of sunlight at a point increases the temperature at that point.
There are many differences between concave and convex mirrors and some of them are as follows.
- CONVEX MIRROR
If outer side of the spherical mirror is reflecting, it is called as convex mirror.
- IMAGE
Convex mirrors form virtual and erect images.
- NATURE
The images formed by the convex mirrors are diminished in nature.
- SIZE
The object in the image formed by the convex mirror look smaller than the original size of the object.
- POSITION
Convex mirrors form virtual and erect images irrespective of the position of the object.
- EXAMPLES
The examples of convex mirrors are the mirrors used as rear side mirrors of vehicles, optical instruments, calling bell, etc.
- USAGE
Convex mirror is used as the rear mirror of the vehicles because, the convex mirror enables a driver to view large area of traffic behind him by forming a small image of the vehicles.
please mark my answer as the brainliest :)
✔✔A concave mirror, or converging mirror, has a reflecting surface that is recessed inward (away from the incident light).
✔ Concave mirrors reflect light inward to one focal point.
✔✔They are used to focus light.
✔✔A convex mirror or diverging mirror is a curved mirror in which the reflective surface bulges toward the light source.
✔✔Convex mirrors reflect light outwards,
✔✔therefore they are not used to focus light.
