Most Asked Questions: Light Reflection And Refraction MCQs
What is the difference between a real and a virtual image?
A real image is formed when rays converge, whereas a virtual image occurs when rays only appear to diverge.
Why are convex mirrors used as rear – view mirror in vehicles?
The reason convex mirrors are used as rear view mirrors in vehicles is they provide drivers with a wider view of what’s behind them.
