Why do we use concave mirror as rear-view mirror?
Convex mirrors are used in car rear view mirrors as they form a smaller image of the object. … Concave mirror on the other hand forms magnified and inverted image of the object. This would form an image of a smaller area and would also inverted which would be hard to understand.
What happens if a concave mirror is used as a rear-view mirror in vehicles?
We cannot use a concave mirror as a rear-view mirror in vehicles because a concave mirror produces inverted images of distant objects. So, all the vehicles will be seen running upside down in the mirror.
Why convex mirror are used in vehicles and not concave mirror?
Convex mirror is commonly used in rear view mirrors in vehicles because it gives an erect, virtual, full size diminished image of distant objects with a wider field of view. Thus, convex mirrors enable the driver to view much larger area which is not possible with a concave mirror.
Can a concave mirror be used as a rear-view mirror?
Hence concave mirrors cannot be used as a rear view mirror. … Since a convex mirror satisfies all the criteria of a rear view mirror. So, the correct answer is “Option B”. Note: The image in a concave mirror Is virtual and erect if the object is placed between the focus and the centre of the mirror.
Why concave mirror is used in vehicles?
The reflected image that is hence created is larger than the actual object. In cars, concave mirrors are found in the headlights as they reflect the light emitted by the bulb in a wider area. This is exactly why the light rays from a bulb of the car’s headlight can reach out to a great distance.
Why concave mirror is not used in vehicles?
A concave mirror always gives a real and inverted image for the distant object which is not suitable for the vehicle. … So we can’t use the concave mirror because it does not give the whole field of view.
What will happen if a concave mirror is used in the experiment?
Answer: If a convex mirror is used instead of concave mirror, the light rays will diverge ,that means they will not fall on the screen, they will go elsewhere. … Rays after reflection on Convex mirror will diverge.
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.
Is rear-view mirror concave or convex?
Convex mirrors have very wide field of view as they are curved outwards. 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.
Why are convex mirrors used as rear view mirrors give two reasons?
We use convex mirror as a rear view mirror in the vehicles because convex mirror always forms virtual, erect and diminished images irrespective of distance of the object. … Convex mirror forms very small image than the object. Due to this reason convex mirrors are used as rear view mirrors in vehicles.
How does a convex rear-view mirror work?
Convex mirrors work two ways. First, they can reflect parallel rays of light in such a way that they scatter in all directions. On the other hand, they can take light coming from various directions and reflect them so that they are parallel. It is this second method that is used in cars.
