Physics of Rainbows

When the light of the sun refracts through a small raindrop falling into the air, a rainbow is formed. The rainbow needs a lot of light from the sun or the moon and spherical raindrops formed in the atmosphere. Rainbows can be compared with mini prisms. The light is refracted ("bends as light passes from one medium to another"), which separates white light of different wavelength (or color). Whether these wavelengths of light pass through raindrops or reflections depends on the angle at which the light illuminates the backside of the raindrop.

Dear, the lunar eclipse is just one of many miraculous miracles in our life experience on the earth. Rainbow is another kind of rainbow. Because the rainbow is a manifestation of the interaction between light and matter, the rainbow is generated by the interaction of the light waves with the particles of water within the angle of 42 degrees specified by the observer. We also experienced the natural wonders of thunder and lightning. Lightning is a hearing experience caused by the expansion of the air near the lightning bolt, "sudden electrostatic discharge occurring during the storm." Even if she assumes her new role as a planet of the five-dimensional creator, the experience of Mother Earth in supporting all natural phenomena in our lives has not changed! So, what is unusual about "American meals?"

Physically, a rainbow appears after the empty storm. It is made up of 7 different colors. Once it is bowed, its shape can be thought of as part of a perfect circle. From the physical size of the rainbow, Shange proposes other qualities appropriate to the liquidity and logic of her dance movement. It seems like a simple natural phenomenon which seems to be natural, but Shanges choreopoem uses rainbow as a complex image to predict changes in weather and changes in life of "colored girls".

This is a good question, we are beginning to consider the physical process of generating a rainbow. When you face a rainbow, most people never notice that the sun is always behind you, and the center of the rainbow arc is opposite to the direction of the sun. Of course, rain is in the direction of the rainbow. Such questions require appropriate physical answers. I will explain the formation of a rainbow of raindrops. This was an optical problem, first discussed clearly by René Descartes in 1637. An interesting history can be found in Carl Boyer's book "The myth to rainbow to mathematics". Descartes simplifies the study of the rainbow and simplifies it to the study of the interaction between water droplets and the light hit by it.
