Raman wants to use a rear-view mirror in his vehicle. Which type of mirror should he pick for it?
Answer & explanation
Correct answer: option 1
The correct answer is option 1. Convex Mirrors.
For a rear-view mirror in a vehicle, Raman should choose a Convex Mirror.
Convex mirrors have a curved reflective surface that bulges outward. This curvature allows them to provide a wider field of view compared to flat mirrors. This is crucial for a rear-view mirror as it allows Raman to see a larger portion of the traffic behind him, including vehicles in his blind spots.
Plane mirrors (flat mirrors) reflect light at the same angle it hits the surface. While they provide a clear image of the area directly behind the car, their field of view is limited. This wouldn't be ideal for a rear-view mirror where a broader perspective is necessary for safe driving.
Cylindrical mirrors and concave mirrors are not typically used for rear-view mirrors. Cylindrical mirrors provide a distorted view, and concave mirrors tend to focus light inward, creating a narrow field of view – both unsuitable for safe driving.
Therefore, a convex mirror offers the wider field of view needed for a safe and effective rear-view mirror in Raman's vehicle.
