Question
- Which type of mirror would you use to focus sunlight to a single point to start afire?A) Plane mirrorB) Convex mirrorC) Concave mirrorD) Cylindrical mirror
Solution
C) Concave mirror
Here's why:
A concave mirror is the type of mirror that would be used to focus sunlight to a single point to start a fire. This is because concave mirrors are designed to reflect light inward to one focal point. They are often used in solar power applications, headlights of vehicles, and in telescopes. When sunlight hits the mirror, it reflects off the mirror's inner surface and converges at a single point. This concentrated point of light can generate enough heat to start a fire.
