Question
1)Is the image formed by a plane mirror is always upright?
2)Is it possible to obtain the image on the screen when the candle is too closed to the concave mirror?
3)Can you get a real image at any distance of the object from the convex mirror?
4)Wha are the uses of plane mirrors, concave mirrors and convex mirrors
Answers
Explanation:
1) Plane mirrors are the only type of mirror for which a real object always produces an image that is virtual, erect and of the same size as the object. Virtual objects produce real images, however. The focal length of a plane mirror is infinity; its optical power is zero.
2)No, we cannot get a real image for any position of an object from the mirror because convex mirror always forms virtual, erect and diminished image in spite of the position of object.
3)Plane mirrors and convex mirrors only produce virtual images. Only a concave mirror is capable of producing a real image and this only occurs if the object is located a distance greater than a focal length from the mirror's surface. 10. The image of an object is found to be upright and reduced in size.
4)Large concave mirrors are used to concentrate sunlight to produce heat in solar furnaces. Convex mirrors are commonly used as rear view mirrors in vehicles because they always give an errect image and have wider field of view as they are curved outwards. Big convex mirrors are used as shop security mirrors.
