Why concave mirror is used in torches searchlights and headlights of vehicles?

A concave mirror is used in headlights of vehicles and torches. The mirror converges beams of light in one direction. Since we would want the beams to travel as far as possible so we can see in the distance , they should be parallel .

Where the image is formed in torch light?

When we shine a torch light on a plane mirror it is reflected on the wall behind as a real image, but all other sources of light (i.e. objects) form virtual images behind the mirror.

Why convex lens is used in torch?

A diverging glass is used in making of a torch light , diverging lens or concave lens is exactly the opposite with the outer surfaces curving inward, so it makes parallel light waves curve outward or divergeand spread out into the distance means it produces a broader range of light.

Are convex mirror used in torches?

Thus when it is used in torches, car reflectors and street lamps, it would diverge the falling rays and thus spread the light and increase the visibility area. Therefore, torches and car reflectors use convex mirrors.

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.

Why torches and headlights gave a parallel beam of light?

Explanation: A bulb is placed at the focal lenght of the concave mirro inside the torch so when the bulb lights up beam of light from focus are reflected by the mirror placed and as per rule of reflection after reflection they goes parallel to the principal axis and hence we obtain a parallel beam of light.

How does a concave mirror used as a reflector in a torch produce a beam of light in the forward direction?

Light bulb is placed at the focus in relation to the torch reflector. When a light bulb is placed at the focus of a concave mirror reflector, then the diverging light rays of the bulb are collected by the concave reflector and then reflected to produce a strong, parallel-sided beam of light.

Does a torch have concave lens?

Solution : (d) Torch – Concave lens is used to spread widely the light produced by a small bulb inside a torch.

Where is the bulb kept of concave mirror in an electric torch?

In a torch the bulb is placed at the focal point of the concave mirror so that the light from the bulb is reflected as a parallel or nearly parallel beam.

Which lens is used by dentist?
