Direct link to Jeff Jordan's post “Say the light hits the dr...” Say the light hits the drop making the angle A with the normal; note that 0°<=A<90°. It bends toward the normal, so it enters at angle B (found with Snell's Law) where 0°<=B<C, and C is the critical angle. Now look at the ray diagrams. The normals all contain a radius of the drop. The path taken by the ray inside the drop makes an isosceles triangle with these radii, meaning it hits the back surface making the same angle B<C. Since total internal reflection only happens when B>=C, it is impossible. (1 vote) NIKHIL SINGH 4 years agoPosted 4 years ago.

Direct link to Divija R's post “If all the light leaves t...” If all the light leaves the droplet ( as in gets refracted by second side of droplet to the outside air), then you will not be able to see a rainbow because only the light that comes back to our eyes after refraction make us perceive the rainbow. A rainbow is visible even after rain because some amount of moisture is still suspended in air and it will disperse and refract light. Rain drops aren’t necessary for rainbows to be seen. Rainbows can also be viewed over waterfalls or fountains- any place that has condensed water droplets suspended in air and sunlight opposite the water droplets.

And last question why don't we see rainbows close to the ground?
If yes, what will happen if that one drop reflects only one color and the rest exit the drop.
If not, what will happen if all those drops reflect only one color and the rest exit the drop?
In the video he said that it is isn’t just one raindrop which refracts and reflects light for the formation of the rainbow because even if it does then we won’t be able to see the rainbow. All the raindrops present in the air will lead to the dispersion of light and only then we will be able to see a rainbow forming. And all the raindrops are scattering all the colours. It’s just that we can see only one colour from one particular raindrop because of the position the raindrop and our eyes.
Hope this helps.
