Question

Assertion(A): refraction index of glass with respect to air is different for red light and violet light.
Reason(R): refraction index of pair of media depends on the wavelength of light used

a)Both A and R are true and R is correct explanation of A
b) Both A and R are true and R is not correct explanation of A
c) A is true but R is false Page 3 of 5 II)
d) A is false but R is true

pls help
​

Answer 1

Answer:

both are true and R is correct explanation of A

Answer 2

The Refractive index of a medium depends is inversely proportional to the wavelength of light used.

Hence, the refractive index of glass wrt to the wavelength used would be different for violet and red.

The assertion is true, and the reason is true, and the reason explains the assertion.

Hence, the answer is A.

The Refractive index is a dimensionless quantity.
