Question

What does the Rainbow look like?

Answer 1

Hint: 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.

Complete step by step solution:
A rainbow is considered to be one of the most magnificent light displays ever seen on the planet. A rainbow is a multicoloured arc formed by light striking water droplets. Rainbows are created after rain by the reflection, refraction, and dispersion of light in water droplets. All of these events produce a light spectrum in the sky, which is known as a rainbow. The rainbow appears as a semi-circle in the sky. Red, orange, yellow, green, blue, indigo, and violet are the seven hues that make up this design. When the sun falls on rain droplets, it creates a natural spectrum of light in the shape of bows in the sky.
Light beams reach the highest level of the descent. Refraction occurs initially, followed by dispersion of white light into colours of different wavelengths.
Violet is the most deviated colour, whereas red is the least deviated.
Due to the entire internal reflection that hits the drop surface, each colour is refracted back into the drop as it reaches the other side.
Every colour is refracted back into the air.
When we view between 42 and 42 degrees, we see a rainbow.

Note:
Rainbows can take the form of complete circles. The viewer, on the other hand, usually only sees an arc created by lit droplets above the ground and centred on a line from the Sun to the observer's eye. The arc of a primary rainbow is red on the outside and violet on the inside. Light is refracted as it enters a droplet of water, reflected internally on the rear of the droplet, then refracted again when it leaves it, resulting in this rainbow. A second arc appears outside the original arc in a double rainbow, with the sequence of the colours reversed, with red on the inner side of the arc. The light is reflected twice on the interior of the droplet before leaving it, which causes this.
