Why are concave mirrors used in solar devices? – InterviewSolution

1.	Why are concave mirrors used in solar devices?
Answer» Solar devices like solar cooker or solar water heater use solar energy to cook food or heat water. When sun rays fall on the concave mirror, they converge and come together in the focal plane. Due to convergence, the intensity of sun rays increases and the food or water is heated faster. Hence, concave mirrors are used in solar- devices.
