Question

When sun rays are passed through a glass prism it gets

• A. Deviated, but not dispersed
• B. Deviated and dispersed
• C. Dispersed, but not deviated
• D. Neither deviated nor dispersed

Answer 1

The correct option is B Deviated and dispersed

Sun rays contain light rays with seven different wavelengths. When these different components pass through a prism, the refractive index of the prism material will be different for different wavelengths. This will cause the splitting of components which is known as dispersion.

On the other hand, deviation in the prism is a general characteristic of light. as there is a change in media the light rays will refract and bend.

So, option B is the correct one.
