    Question

    Which of the following does not refract light?

    1. Air
    2. Water
    3. Glass 
    4. Wood

    Hint:

    Air, water and glass are transparent medium.

    The correct answer is: Wood

      • When light ray goes from one transparent medium to another transparent medium it changes its path this phenomenon is called refraction .
      • Wood is an opaque object.
      • So, the correct option is d.
