Question

Rainbow is an example for continuous spectrum. Explain

Answer 1

Rainbow

1. A rainbow is formed when the sunlight is scattered by the water drops which are suspended in the air.
2. Sunlight has different frequencies and all are scattered by the raindrop.
3. It is formed in multi-colors.
4. It has 7 colors.

A diagram to represent the rainbow:

Continuous spectrum

1. It is an emission spectrum consisting of continuous wavelengths

Rainbow as a continuous spectrum

1. The rainbow is formed by scattering of the sunlight by water droplets present in air.
2. The sunlight is scattered into all of its different frequencies and, therefore, can be called, a continuous spectrum.
3. The wavelength which they emit has a broad range.
4. Therefore, the spectra appear continuous and smooth.

Hence, rainbow is an example for continuous spectrum.
