(i) Why is the ratio of the velocities of light of wavelengths 4000Å and 8000Å in vacuum 1 : 1 ?(ii) Which of the above wavelengths has a higher frequency ? |
|
Answer» (i) In vaccume light or any electromagnetic wave velocity is always constant 3 × 108 m/s and it does not depend on wavelength or frequency. (ii) As we know v n, where v = velocity and „n‟ is frequency, therefore frequency is inversely proportional to wavelength. therefore wavelength of 4000Å will have more frequency. |
