Monochromatic ray of light incident on a glass prism does not produce the phenomenon of
Monochromatic ray of light incident on a glass prism does not produce the phenomenon of
Show Hint
White light is polychromatic. A prism disperses white light because different colors have different speeds in glass.

- dispersion
- refraction
- deviation
- reflection
- total internal reflection
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
Dispersion is the splitting of white light into its constituent colors due to the variation of refractive index with wavelength.
Step 2: Detailed Explanation:
Monochromatic light consists of a single wavelength (or a very narrow band of wavelengths). When it passes through a prism, it will refract (bend), deviate from its original path, and may undergo partial reflection or even total internal reflection at the second face depending on the angle. However, since there is only one wavelength, there is no splitting into different colors. The phenomenon of dispersion (splitting of light into colors) does not occur.
Step 3: Final Answer:
A monochromatic ray does not produce dispersion.
