Which mirror is used in solar cooker?

concave mirror
Note: A plane mirror can be used in a solar cooker but it cannot concentrate the rays at point as the concave mirror does. Thus, the maximum heat will not be achieved. A convex cannot be at all since it will diverge away the sun rays falling on it.

Who was the Roman soldier that killed Archimedes?
