What is the difference between concaveand convex mirrors
Answers
If inner side of spherical mirror is reflecting, it is called as concave mirror. If outer side of the spherical mirror is reflecting, it is called as convex mirror.
IMAGE
Concave mirrors form real and inverted images. Convex mirrors form virtual and erect images.
NATURE
The images formed by the concave mirrors are magnified in nature. The images formed by the convex mirrors are diminished in nature.
SIZE
The object in the image formed by the concave mirror look bigger than the original size of the object. The object in the image formed by the convex mirror look smaller than the original size of the object.
POSITION
Concave mirrors form real and inverted images except when the object is between pole and focus. Convex mirrors form virtual and erect images irrespecive of the position of the object.
EXAMPLES
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.
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. 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
