Convex mirror
The side mirrors of the car and the rear view mirror of a car are made up of convex mirrors. This is because the image formed by a convex mirror is diminished and erect image, thus it provides a larger field of view.
What is the magnification produced by a concave mirror?
In case of convex mirror, magnification is always less than one. However, in case of concave mirror the magnification may be less than, equal to or greater than one.
What will be the size of image in rear view mirror?
We are given a convex mirror. A virtual and erect image of height 2.2 cm is formed behind the mirror (because v is positive) at a distance of 8.6 cm from the mirror.
What kind of image is formed by the rear view mirror?
In rear view mirrors, convex mirrors are used. They form virtual and erect images.
Which mirror is used as a rear-view mirror Why?
So, the convex mirrors enable the driver to view much larger area than a plane mirror. The images produced are erect and their size is much smaller than the object. Hence, it is used as a rear view mirror in automobiles to see objects at the backside of the vehicle.
What is the magnification of convex mirror?
The image formed by a convex mirror is always smaller in size than the object; hence its magnification is less than 1.
What is the magnification produced by a convex mirror?
A convex mirror always creates a virtual image which is diminished. So, magnification produced by convex mirror is always less than one. Was this answer helpful?
What is the magnification of concave mirror and convex mirror?
Magnification of a convex mirror is always positive, but that of a concave mirror may be both positive or negative.
What is the magnification produced by a rear?
Convex mirrors are used in vehicles for rearview due to their wide field of view. And the convex mirror forms a virtual, erect and diminished image of the object. Therefore, magnification (m) produced by a rearview mirror fitted in vehicles is less than one.
What is the mirror formula?
Let’s explore the mirror formula (1/f = 1/v+1/u) and see how to locate images without drawing any ray diagrams.
Which mirror is used as a shaving mirror as a rear view mirror in vehicles?
A concave mirror is used in a shaving mirror because when the concave mirror is placed very close to the object, a magnified and virtual image is obtained. A convex mirror is used as a rear-view mirror in vehicles because it forms a diminished erect image.
What is the nature of the image formed by a plane mirror?
A plane mirror always forms a virtual image (behind the mirror). The image and object are the same distance from a flat mirror, the image size is the same as the object size, and the image is upright.
Why is not possible to capture an image formed by a convex mirror?
It always forms virtual, erect, and diminished images irrespective of the distance between the object and the mirror. From the above explanation, we can conclude that we cannot capture the image produced by a convex mirror because it forms a diminished (very small) image and that too behind the mirror.
What is lateral inversion?
Lateral inversion is the reversal of mirror image where the right side of the object appears on the left side behind the mirror.
