Color Dispersion | MCQs

Explanation

• When light passes through a prism, refraction occurs, leading to the formation of a spectrum.
• Refraction is the bending of light as it passes through a medium with a different optical density.
• It causes the different wavelengths of light to separate and form a spectrum.

Explanation

• A rainbow is a beautiful natural phenomenon that demonstrates the spectrum of white light.
• When sunlight passes through water droplets in the air, it is refracted and separated into its individual colors, creating the colorful arc of a rainbow.
• This is a perfect example of the spectrum of white light.

Explanation

A spectrum is a band of seven colors that appear when white light is passed through a prism or a similar device, separating the different wavelengths of light.

The seven colors of the spectrum, in order, are:

1. Red
2. Orange
3. Yellow
4. Green
5. Blue
6. Indigo
7. Violet

Explanation

• Dispersion of light refers to the splitting of white light into its component colors, which are also known as the visible spectrum.
• This occurs when light passes through a medium with a refractive index that varies with wavelength, such as a prism.
