Which application does a concave mirror serve?

A concave mirror is designed to converge light rays to a focal point, making it particularly useful in applications where focused light or magnification is desired. This characteristic is what makes concave mirrors effective in solar ovens. In a solar oven, the concave mirror reflects sunlight into a single point where the heat energy is concentrated, allowing the oven to heat up efficiently for cooking purposes.

While the other options involve mirrors, they typically utilize different types. Security mirrors are often convex to provide a wider field of view, which is helpful for monitoring larger areas. Car side mirrors are likewise convex to minimize blind spots and provide a broader perspective of the area around the vehicle. Bathroom mirrors are generally flat or slightly curved, allowing individuals to see reflections without distortion. Thus, the unique properties of concave mirrors for focusing light make them particularly suitable for solar ovens.
