- Solar cooker: It is a device that uses the energy of sunlight to heat or cook food.
- Concave mirror: The mirror whose reflecting surface is toward the center of the curvature is called a concave mirror. It is also known as a converging mirror.
EXPLANATION:
- Concave mirrors are the mirrors best suited to be used in solar cookers because they are the only types of mirrors that reflect sunlight towards a single focal point. Therefore option 3 is correct.
- As we know the convex mirror is known as a diverging mirror, as they diverge the incident rays after reflection. So, if it is used in a solar cooker, then it will not work as they are unable to converge light rays to a single point. Therefore option 2 is incorrect.
- Plane mirrors can be used because it helps in absorbing heat and is a good reflector but is not the best-suited mirror. Therefore option 1 is incorrect.
