Dispersion of light is due to
Text Solution
Verified by ExpertsThe correct answer is:
A
Step 1: Understand the concept of dispersion of light. Dispersion occurs when different wavelengths of light bend at different angles when passing through a medium, such as a prism.
Step 2: Recognize that the degree of bending (refraction) is dependent on the wavelength of light. This phenomenon is described by Snell's Law.
Step 3: Consider the options provided:
Step 2: Recognize that the degree of bending (refraction) is dependent on the wavelength of light. This phenomenon is described by Snell's Law.
Step 3: Consider the options provided:
- Option A: Wavelength - Correct, as different wavelengths refract differently.
- Option B: Intensity of light - Incorrect, as intensity does not affect the angle of dispersion.
- Option C: Density of medium - While density can influence how light behaves in a medium, the essential cause of dispersion relates specifically to wavelength differences.
- Option D: None of these - Incorrect, as wavelength is indeed the correct answer.
