Convex mirrors are used widely as reflectors for street light bulbs as it diverges light ray over a wide area.Answer. Convex mirror is used in street light because it has the property of divergence . Therefore light rays coming from bulb diverges in convex mirror and cover a large distance . In case of a concave mirror ,it has property of convergence .A plane mirror is used in a microscope, mirror tiles, for signaling and periscopes. Hence, comparing all the given options, it can be concluded option B is correct; a street light bulb uses the convex mirror as reflectors.

Why is a concave mirror used in torches while a convex mirror is used in street lamps?
It ia for this purpose that it is used in street lamps as it would diverge the light rays and hence spread the light so that visibility increases. On the other hand concave mirror is also called converging mirror. It is used for different light rays falling on it to a single point.

Why are convex mirrors used on roads?
Lateral visibility at road junctions can be improved by a convex mirror. Mainly in built-up areas, where visibility on one or both sides of an intersection may be hampered by space limitations, such a device is attractive because of its low cost and its actuated operating mode.
Where are convex and concave mirrors used?
When parallel beams of light fall on the concave mirror it converges the light beam at a point called the focus. That’s why a concave mirror is called a converging mirror. Uses of convex mirrors are following: Convex Mirror is used as a rearview mirror in vehicles to see the traffic at the rear side.
Where is concave mirror used?
Concave mirrors are widely used in automobiles and motor vehicles headlights, torchlights, railway engines, etc. as reflectors. The light source is placed at the focus of the mirror, so after reflecting the light rays travel over a huge distance as parallel light beams of high intensity.
What are concave mirrors?
A concave mirror, or converging mirror, has a reflecting surface that is recessed inward (away from the incident light). Concave mirrors reflect light inward to one focal point. They are used to focus light.
Why convex mirrors are used in vehicles for rear-view?
Convex mirror is commonly used as rear-view mirror in vehicles because they always give an erect image and have field of view as their curved outwards.
Are car mirrors 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. A larger field of view helps the driver to know better about the traffic behind.
Is dentist mirror concave or convex?
A concave mirror gives the dentist a magnified reflection of the mouth while also refracting a bit of light. This means the image in the mirror is larger, brighter, and, for the dentist, easier to see.
Which mirror is used in bike?
The convex mirror produces an upright image of any object and offers a wide viewing area as compared to the plane mirror. The usage of this type of mirror can be perceived on the car rear-view mirror, side-view mirror and even the motorcycles.
Is magnifying glass concave or convex?
Magnifying glasses
A magnifying glass is a convex lens used to make an object appear much larger than it actually is. This works when the object is placed at a distance less than the focal length from the lens.

Which lens is used in flashlight?
Concave lenses are also used in flashlights to magnify the light produced by the source. The light rays fall on the hollowed side of the lens, and the light rays diverge on the other side. This increases the radius of the light source and thus provides a wider beam.
What are the 5 uses of concave mirror?
Concave mirrors are used as headlights, torches, head mirrors, solar furnaces, microscopes, telescopes, etc.
