Question

Give the ratio of velocity of light ray of wavelength 4000 A and 6000 A in vacuum

Answer 1

Answer:

$\frac{4000}{6000} = \frac{4}{6} = \frac{2 \times 2}{2 \times 3} = \frac{2}{3} = 2 : 3$

Answer 2

Answer: 1:1

Explanation: because both are electromagnetic radiations .

All electromagnetic radiations travel in vacuum with the same Speed and thus the ratio of the velocities of these two wavelengths will be 1:1
