At the time of the rainbow, the raindrops in the atmosphere act like.

Explanation

Solution

A rainbow is a meteorological phenomena that occurs when light is reflected, refracted, and dispersed in water droplets, resulting in a spectrum of light seen in the sky. It's shaped like a multicoloured circular arc. Sunlight-induced rainbows always appear in the sky region directly opposite the Sun.

Complete step-by-step solution:
Rainbows are created when sunlight is dispersed by water droplets (such as raindrops or fog) in a process known as refraction. When sunlight passes through a material denser than air, such as a raindrop, it refracts, changing its direction. When light enters the raindrop, it is refracted, reflected off the back, and then refracted again as it departs and travels to our eyes. When sunlight passes through a material, it is made up of several distinct wavelengths, or colours, which move at different rates. The white light is divided into multiple colours as a result of this. Shorter wavelengths appear as blue or violet, whereas longer wavelengths appear as red. As light travels through the raindrop at different angles of roughly two degrees, we observe the rainbow's colour spectrum, which ranges from red to violet. The colours mix and blur throughout the show, so this isn't a complete spectrum. Because the angle of dispersion from raindrops differs for each individual, each rainbow is unique to the viewer. A water droplet catches the light. Because light travels slower in water than in air, it bends or refracts a bit as it passes through the droplet (water is denser). The light then bounces off the rear of the water droplet and returns in the same direction it came, bending again as it exits the water droplet. Raindrops in the sky function as numerous tiny prisms as a rainbow appears.

Note: A rainbow is an optical illusion created by any water droplets viewed from a certain angle relative to a light source. It is not positioned at a certain distance from the observer. As a result, a rainbow is not a tangible thing that can be approached. Indeed, any angle other than 42 degrees from the direction opposite the light source prevents an observer from seeing a rainbow formed by water droplets. Even if another viewer seems to be "beneath" or "at the end of" a rainbow, the second observer will see a separate rainbow—further away—at the same angle as the first observer.
