Red light differs from blue light as they have: (a) Different frequencies and same wavelengths (b) Different frequencies and different wavelengths (c) Same frequencies and different wavelengths (d) Same frequencies and same wavelengths

Answer: (b). Colour is set by frequency, so red and blue have different frequencies. In the same medium λ = v/f, so their wavelengths also differ. So the answer is (b).

Refraction, Glass Slab & Apparent Depth

Red light differs from blue light as they have:

Show answer and solution

Answer: (b)

Colour is set by frequency, so red and blue have different frequencies.
In the same medium $\lambda = \frac{v}{f}$ , so their wavelengths also differ.
So the answer is (b).
