Question

In practical applications [like in car – headlights] concave mirrors are of __________ shape​

Answer 1

Answer:

When the bulb of headlight is placed at focus of concave mirror, it allows the light to spread out to infinity (longer distances) and at infinity they are approximately parallel. Hence, concave mirrors are used in the headlights of vehicles.

Answer 2

Spherical shape

• Concave mirrors are used in vehicle headlights because placing the bulb at the focus on the concave mirror allows the light to travel through infinity after reflecting off the mirror .
• A mirror is a surface that reflects almost any light that falls on it .
• The mirror may have a flat or curved surface . A mirror with a flat surface is called flat , and a mirror with a curved surface is called spherical . Learn about convex and concave mirrors in this article .
• A mirror is a reflective surface that reflects light and creates a real or imaginary image .
• If you place an object in front of a mirror , you will see the reflection of the same object in the mirror .
• The object is the source of the incident light , and the image is formed by the reflected light .
• Depending on the intersection of the rays , the image is classified as a real image or a virtual image .
• The true picture is created when there is light .
