Where is a convex mirror used?
Think it through first, then pick an option.
- a in cars
- b in a torch light
- c in a solar cooker
- d in a radar
Answer and explanation
Correct answer: a in cars
A convex mirror gives an upright, smaller image, so it is used as the rear-view mirror of cars to see a large scene in a small space. A torch light has a concave mirror; solar cookers and radar are not in this book.
Why the other options are wrong
- b in a torch light: This is not the answer: A convex mirror gives an upright, smaller image, so it is used as the rear-view mirror of cars to see a large scene in a small space. A torch light has a concave mirror; solar cookers and radar are not in this book.
- c in a solar cooker: This is not the answer: A convex mirror gives an upright, smaller image, so it is used as the rear-view mirror of cars to see a large scene in a small space. A torch light has a concave mirror; solar cookers and radar are not in this book.
