With the help of a labeled diagram, explain the construction and working of a solar cooker.
Solar cookers vary in design, but many feature a chamber lined with reflective surfaces, such as aluminum foil and a clear, plastic or glass window, through which the sunlight enters. When sunlight passes through plastic or glass, its spectrum shifts, and much of the ultraviolet radiation is filtered out. However, this filtered light transforms into heat, which raises the temperature inside the solar cooker.
