correct the mistake in the sentence . The sunlight goes through the rain drops

The sentence "The sunlight goes through the rain drops" is actually not incorrect grammatically or structurally, but if we're aiming to describe the phenomenon where sunlight interacts with rain to create a rainbow, a more scientifically accurate sentence could be "The sunlight is refracted as it passes through the raindrops." This statement provides a clearer idea of the process occurring between sunlight and raindrops, known as refraction.

Refraction is the bending of light as it passes from one medium to another, such as from air into water. When sunlight encounters raindrops in the atmosphere, the different colors of light are bent at slightly different angles due to their varying wavelengths. Because of this, the light separates into a spectrum of colors, creating the appearance of a rainbow. This phenomenon is most often observed when the sun is low in the sky behind the observer and rain is falling in front of them, which provides the perfect conditions for the sunlight to be refracted and dispersed by the raindrops.
