Convex mirror is generally used in ________ A. Solar cookers B. Opthalmoscope C. Reflector for head light D. Rear view mirror

The correct answer is: D. Rear view mirror.

A convex mirror is a curved mirror in which the reflecting surface bulges outward at the center. Convex mirrors are used in rear view mirrors because they provide a wider field of view than plane mirrors. This is because the reflected image is smaller and farther away than the object being viewed. This makes it easier to see what is behind the car when backing up.

Solar cookers use concave mirrors to focus sunlight onto a small area, which heats up food or other objects. Opthalmoscopes use concave mirrors

to reflect light into the eye, so that the doctor can see the inside of the eye. Reflectors for headlights are usually made of parabolic mirrors, which are a type of concave mirror that focuses light into a single point. This allows the headlights to project a bright beam of light down the road.

In conclusion, convex mirrors are generally used in rear view mirrors because they provide a wider field of view than plane mirrors.
