Why is it that the extent of the doppler effect on sound depends on whether, for example, you are moving towards the source or the source is moving towards you? Why does this not happen for light?

Dear nitin,

It does happen for light (how do you think that cop knew how fast you were driving?). But since the speed of light is a lot faster than the speed of sound, you have to be moving a lot faster (or have sensitive equipment) to notice it.

We are all IITians and here to help you in your IIT JEE preparation.

All the best.

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
