Assertion (A): Refractive index of glass with respect to air is different for red light and violet light.
Reason (R): Refractive index of a pair of media depends on the wavelength of light used.
Answer
-
Since angle of refraction
of red and violet light
is different,
their
Refractive index
is
also different
- Refractive Index and Wavelength are related: Refractive index is inversely proportional to wavelength
Thus,
- Assertion is true
- Reasoning is true
- And reasoning is the correct explanation of assertion
Correct option: (a)
