We cannot use a concave mirror as a rear-view mirror in vehicles because it forms an inverted image of the distant objects (object at a large distance), due to which all the vehicles will be seen running upside down in the mirror.
Why only convex mirror is used in vehicles?
We prefer a convex mirror as a rear-view mirror in vehicles because it gives a wider field of view, which allows the driver to see most of the traffic behind him. … Convex mirrors always form an erect, virtual, and diminished image of the objects placed in front of it.
Why is plane mirror not used in vehicles?
A plane mirror cannot be used because it does not converges light. In order to see traffic at the back, the convex mirror is used because it converges the light. It forms a virtual, erect and diminished image.
Can a concave mirror be used in side view mirror of the vehicles Why?
Convex mirrors are used as side view mirrors in a car to see the traffic behind. This is because of the following reasons: The image formed in a convex mirror is highly diminished due to which a convex mirror gives a wide field of view of the traffic behind the vehicle.
What happens if we use concave mirror as rear-view mirror in vehicles?
If a concave mirror is used as a rearview mirror of a vehicle as a concave mirror produces the completely inverted image of the real image to be produced. When we use a concave mirror the image of the distant object gets inverted so it is not physically possible to use them.
Why concave mirror is used in headlights of vehicles?
In case of head lights of vehicles, the bulb is placed at focus so that all the light rays after reflection go in parallel lines. Due to these parallel rays, it allows the light to go at infinity and we can see the objects far away from vehicle. Thus concave mirror send parallel rays. Hence option 2 is correct.
Why convex mirror is used as rear view mirror and not a plane mirror?
A convex mirror is used instead of plane mirror because it has large view angle with always an erect image formation irrespective of position of object.
What are the advantages and disadvantages of using concave mirror for seeing traffic at the rear?
Answer: advantage : we could see large image of theobject before it arrives. disadvantage : because of its inverting image we could not see a full view of the object also we cannot see a full area in one view.
Why do we prefer to use concave mirror as rear view mirror?
Erect image helps in identifying the object easily. Diminished image increases the field of vision also objects located far away can be seen closely with convex mirror. All these above mentioned things allow the driver to see most of the traffic behind him. Hence convex mirror is always preferred as rear-view mirror.
Is car side mirror concave or convex?
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 are the differences between concave mirror and convex mirror?
A concave mirror is a spherical mirror with an inwardly curved reflection surface, whereas a convex mirror is a spherical mirror with an outwardly bulged reflecting surface.
