    Which of the following parts of the sunlight makes the

    solar cooker hot?
    A Ultra violet Correct Answer Incorrect Answer
    B Red light Correct Answer Incorrect Answer
    C Infra red Correct Answer Incorrect Answer
    D Cosmic rays Correct Answer Incorrect Answer

    Solution

    Glass transmits visible light but blocks infrared thermal radiation from escaping. This amplifies the heat trapping effect. A solar cooker, or solar oven, is a device which uses the energy of direct sunlight to heat food or drink to cook it or sterilize it. The vast majority of the solar cookers presently in use are relatively cheap, low-tech devices.
