                    Colours of thin soap bubbles are due to:                                                                                              

    A)                 refraction

    B)                 dispersion                          

    C)                 interference   

    D)                 diffraction

    Correct Answer: C

    Solution :

                    When white light is incident on a soap bubble it is partly reflected from upper surface and partly reflected from lower surface. These two reflected beams superpose to cause interference. The colours which satisfy the condition of maxima are visible in reflected light. So, colours of soap bubbles are caused due to interference.
