Question

Formation of spectrum by a glass prism takes place because:

• A. the light of different colors have different intensities
• B. the light of different colors refract with different angles of refraction
• C. the light of different colors have different energies
• D. the light of different colors have different frequencies

Answer 1

The correct option is B

the light of different colors refract with different angles of refraction

Different colours of light are refracted at different angles. This difference in the angles of refraction of different colours during refraction results in a colourful spectrum.
