Question

Rainbow is formed in which direction with respect to the Sun?
(A) Same direction
(B) Opposite direction
(C) Depends on the time of the day
(D) North direction

Answer 1

Hint:In order to answer this question, to know the direction of the rainbow with respect to the Sun when it forms, we will describe the whole formation of the rainbow, and also we will discuss why it forms in a particular direction with respect to the Sun.

Complete step-by-step solution:
A rainbow is always generated in the opposite direction of the Sun, so that sunlight striking on water droplets (which act as prisms) can be easily refracted and dispersed, resulting in a rainbow.
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 area directly opposite the Sun.
Rainbows can take the form of entire circles. The viewer, on the other hand, usually only sees an arc created by lighted droplets above the ground, 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 when it enters a droplet of water, reflected internally on the rear of the droplet, then refracted again as it leaves it, resulting in this rainbow.
A second arc appears outside the primary 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 inside of the droplet before leaving it, which causes this.
Hence, the correct option is (B) Opposite direction.

Note:The sun's light is refracted by the raindrop, which is then internally reflected and refracted. The sun is in the direction of the emerging rays. As a result, for a person standing on the sun's side, the rainbow's rays emanate from the opposite side of the sun, making the rainbow appear to be on the opposite side of the sun.
