The Secret Of Rainbow

     A rainbow is a natural phenomenon that occurs after every rain. The rainbow forms beautiful colors in the sky that appear on the horizon curved from one end to the other. This natural phenomenon of the rainbow is explained by physicists as the event of refraction of sunlight. Sunlight is polychromatic light. A rainbow or a Ferris wheel is an optical and meteorological phenomenon in the form of multicolored, parallel light that appears in the sky or other medium. In the sky, the rainbow appears as an arc of light with its tip pointing to the horizon at a time of light rain. A rainbow can also be seen around the heavy waterfall. Rainbow has 7 colors consisting of Red Orange Yellow Green Blue Tilapia Purple

     A rainbow occurs because of the light habituation. Light passing through two different mediums will experience habituation and change in direction. This deflection occurs because light travels at different speeds when passing through different media. That also causes white light to be separated based on its frequency

   

    The rainbow will not appear at night or in cloudy weather. That happens because the rainbow is the result of refraction of light. The rainbow can only be seen when it rains with the sun shining but from the opposite side of the observer. The observer's position must be between the sun and the drop of water with the sun behind the person. The sun, the observer's eyes and the center of the rainbow must be in a straight line. The light with the shortest wavelengths like purple, is on the curve and the longest wavelengths like red are on the outside
