You can't with your eye. You'd need to use a spectrograph and compare the spectrum coming out to radiation or absorbtion from elements at rest.

u can observe doppler effect at the bus stand or at the railway station . when a train approaches the platform the frequency of sound of the train changes. similarly as the train leaves the platform the sound frequency changes differently. the case is the same if the train were to be stationary and u were to move. but in this case the change in frequency will be different. finally if both of u were to move the frequency will change and yet at a different rate

There is an easy way. You only have to listen to a train approaching to you and to another going far away from you. The sound is different and it's because the Doppler effect.

Actually, you can hear the doppler effect when a train whistle is coming toward you and passing you. The whistle will change pitch as it nears you and become higher. This is the same as changing color in light.

You can hear it whenever a car speeds by you. It is that zooommm sound that starts out high and goes lower after the car passes. To see it in light without instruments, you would need to be passed by something moving at a significant fraction of the speed of light, at many millions of miles per hour.
