Solution
- Concave mirrors:
- Concave mirrors are used while applying make–up or shaving, as they provide a magnified image.
- They are used in torches, search lights, and head lights as they direct the light to a long distance.
- Convex mirrors:
- Convex mirrors are used in vehicles as rearview mirrors because they give an upright image and provide a wider field of view as they are curved outwards.
- They are found in the hallways of various buildings including hospitals, hotels, schools, and stores. They are usually mounted on a wall or ceiling where hallways make sharp turns.
