We see rainbows because of the geometry of raindrops. When the sun shines from behind us into the rain, incident rays of light enter the drop and are refracted inwards. They are reflected from the back surface of the raindrop, and refracted again as they exit the raindrop and return to our eyes.

Why do we see rainbow after a rain shower?
AFTER A RAIN SHOWER, VERY TINY RAINDROPS REMAIN DISPERSED IN THE AIR. THESE RAINDROPS ACT LIKE TINY PRISMS. WHEN THE SUNLIGHT PASSES THROUGH THESE RAINDROPS AT A PARTICULAR ANGLE, THESE RAINDROPS ACT LIKE SMALL PRISMS AND SCATTER THE BEAM OF LIGHT IN SEVEN COLOURS. IN THIS WAY A RAINBOW OCCURS.
