Question

Explain two activities for the formation of artificial rainbows?

Answer 1

Hint-An artificial rainbow can be created by emitting light from any wavelength (not a monochromatic source of light) along with some water. Using these to think about the things which can help to shape an artificial rainbow.

Complete step-by-step answer:

Operation first
They take a small bowl and a glass.
The tank is brimming with water.
A bottle is inserted in the cup.
The bowl that includes water and glass is held in front of a window where sunlight passes in.
When the sunlight falls on the glass, an artificial rainbow is created directly to the window at the wall.

Second operation
A glass prism is being confiscated.
Sunlight is used, or a white light torch.
When the sunlight or white light falls on the prism it reveals the seven colors that are a rainbow artificial.
Through the prism we can see the colours.
So that's the response they need.

Additional information - A natural rainbow is basically formed by three basic criteria that is reflection, refraction and dispersion of light. Reflection is accompanied only if the light to be reflected passes through the same medium that is the refractive index does not change all throughout the transmission. In case of refraction the light used to travel from a medium having a different refractive index to that of a medium having another different refractive index. Dispersion refers to the phenomena of splitting up of light into its corresponding component based upon the corresponding wavelength.

Note - Due to reflection , refraction and light dispersion in water droplets, a natural rainbow is created. As light consists of violet, indigo, blue , green, yellow , orange , red and so on color spectrum. As this effect results in the presence of a spectrum of light in the sky. So artificial rainbows can be created when we can conduct certain phenomena artificially.
