Nope. It's caused by refraction.
Refraction and total internal reflection of sun's radiation in fine droplets of water cause rainbow formation
total internal reflection
It is used in optical fibers. It is also the reason we see a rainbow and why diamonds have their brilliance.
rainbow rainbow is not example of tir bec. glory is an optical phenomenon produced by light backscattered (a combination of w:diffraction, reflection and w:refraction) towards its source by a cloud of uniformly-sized water droplets.
periscope is an example of total internal reflection.
you can demonstrate total internal reflection using a light source and glass gratings.
balls
total internal reflection
False.
Total Internal Reflection
yes
Rainbow is made from refraction & total internal reflection of light of the sun. The light of sun is white, which is combination of 7 colours. When rainbow occoures, white light is divide into all these colours. That's why rainbows have many colours.
