Enlist two observation as a beam of white light passes through a glass prism
Answers
Explanation: In 1665, Isaac Newton discovered that white light consists of seven colours. He found that if a beam of white light is passed through glass prism then it will split in to seven colours. These colours are red, orange, yellow, green, blue, indigo and violet (VIBGYOR).
Answer:
When a beam of light passes through a glass prism, the following observations occur:
After the passing of light through a glass prism, it bends.
The light gets separated into its
components colors i.e. red, green,
blue, orange, yellow and violet.
• This phenomenon is known as the dispersion of light.
Red light deviates the least on passing through the prism as it has the largest wavelength.
On the other hand, violet light deviates the most upon passing through the prism as it has the shortest wavelength.
