This technique uses the fact that if a star … WebWhen an object moves relative to an observer who is stationary or moving, changes in sound and light are observed, which is called the Doppler phenomenon. When the light source or the receiver moves, the color of receiving light will change. When an object moves away from receiver we have redshift. It means the light is shifted to the red spectrum. And if … WebIf, the object is moving away and is experiencing a blueshift, where z is the cosmological redshift. If, there is a redshift and the object is moving away from the observer. This effect is used to determine the position and other characteristics of objects in space, such as satellite velocity and position. It’s also utilized in radar systems. safe is smart scholarship
