    Solution:

    Concept: The diapason has lots of shafts that are infrared shaft, ultraviolet shaft,x-ray, visible shaft, micro shaft, radio shaft, gamma- shaft.  If we arrange those shafts in order of wavelength also the order will be  gamma- shaft shaft< visible shaft< infrared shaft< micro shaft< radio shaft
    And the frequency order will be the contrary of this order.
    gamma- shaft>x-ray> ultraviolet shaft> visible shaft> infrared shaft> micro shaft> radio shaft
    In those shafts only visible shafts we can see because visible shafts have color.
    Visible shafts have seven colors that are present in it which are red, violet, green, orange, indigo, blue, and unheroic.
    The wavelength order of those 7 colors are violet< indigo< blue< herbage< yellow< orange< red
     and frequency order of those colors would be  violet> indigo> blue> green> unheroic> orange> red .
    In the sky, the colors which have high frequency will scatter further because violet, indigo, and blue have a high frequency so that colors scatter more in the sky and all those colors look like blue that is why the sky looks blue.
    Hence, the correct option is 2.
