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 is concave mirror not used in vehicles?
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.
Which concave mirror used for the headlights of a car is?
The Correct Answer is concave mirror. A concave mirror is used in a car headlight. The explanation is that a concave mirror is a converging mirror, as opposed to a convex mirror, which is a diverging mirror.
Why plane mirror is not used in headlights of 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.
Why concave mirror is not used in street lights?
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 . So it can’t cover a long distance like convex mirror …
Why are concave mirrors used in car headlights and flashlights?
Concave mirror are used in car headlamp. Concave mirror has converging power, it can concentrate the light ray at a particular point. And in night we want highly concentrated light beam for clear visibility. This is why concave mirror is used.
What would happen if we are not using any kind of mirror in a vehicle?
Answer: Explanation: Driving without side mirrors makes it nearly impossible to safely maneuver your vehicle on the road. They’re designed to give you visibility of up to 200 feet behind your vehicle, which is essential when you’re overtaking, switching lanes, turning, and parking.
Why is convex mirror used in vehicles?
These convex mirrors are used for cars because they give an upright image and provide a wider field of view as they are curved outwards.
Why do dentists use concave mirrors?
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. Another plus of using a concave mirror is that the image in the mirror isn’t inverted.
Which mirror is used in headlights of a car and why?
A concave mirror or otherwise known as a converging mirror has a reflecting surface that is recessed inward. When an object is placed at its focus it produces its respective image at infinity (see figure). Thus they are used to focus light. Therefore, concave mirrors are in headlights of vehicles as reflectors.
Why are convex mirror used in street lights?
A convex mirror is used as a reflector in a street light because it diverges rays of light over large area. A convex mirror is used as a reflector in a street light because it diverges rays of light over large area.
Why do we use convex mirror in street lights?
Convex mirrors are used as reflectors in street lights because they are able to spread the light over a wide area.
