Question

class 10 the formation of Rainbow ​

Answer 1

Answer:

rainbow is a natural spectrum of sunlight in the form of bows appearing in the sky when the sun shines on rain drops. It is combined result of reflection, refraction and dispersion of sunlight from water droplets, in atmosphere. Always it formed in the direction opposite to the sun. ... Thus, we see a rainbow.

Answer 2

Answer:

Rainbows are formed when light from the sun is scattered by water droplets (e.g. raindrops or fog) through a process called refraction.

Explanation:

Once the refracted light enters the raindrop, it is reflected off the back and then refracted again as it exits and travels to our eyes. Sunlight is made of many different wavelengths, or colours, that travel at different speeds when passing through a medium. This causes the white light to split into different colours. Longer wavelengths appear as red and shorter wavelengths appear as blue or violet. We see the colour spectrum of the rainbow as the light passes through the raindrop at different angles of approximately two degrees, from red to violet.
