Prism, Dispersion & Scattering
Given below are two statements:
Statement I: When the white light passed through a prism, the red light bends lesser than yellow and violet.
Statement II: The refractive indices are different for different wavelengths in dispersive medium. In the light of the above statements, choose the correct answer from the options given below:
Show answer and solution
Answer: (a)
- Statement II: in a dispersive medium depends on wavelength, roughly: true.
- Statement I: red has the longest , smallest , so it bends least: true.
- So the answer is (a) both are true.
