![]() ![]() Since experiencing a gravitational force is equivalent to being in an accelerated reference. Red Shift allowed Alicia to go as he opened a portal to reveal a black hole intended to ensnare the Silver Surfer, but its gravity pulled both of them inside. ![]() This phenomenon is called the gravitational red shift. Light emitted at a lower level in a gravitational field has its frequency reduced as it travels to a higher level. The redshift values for these celestial bodies were then used to infer additional information about them, such as velocity relative to Earth and distance from Earth. L is the length of the invariant interval OB. Doppler effect example: Sound waves from a police car siren. As an object moves away from us, the sound or light waves emitted by the object are stretched out, which makes them have a lower pitch and moves them towards the red end of the electromagnetic spectrum, where light has a longer wavelength. By calculating the difference in wavelength between the body’s absorption spectrum and Hydrogen’s emission spectrum, a redshift value, z, was determined. Redshift is an example of the Doppler Effect. The spectrometer was used to measure the absorption spectrum of the bodies and then these absorption spectrums were compared against the Hydrogen emission spectrum. This was done using a high-resolution near ultra-violet spectrometer in conjunction with a 14-inch Celestron Schmidt-Cassegrain telescope. In this study, redshifts were observed in the spectrographic observations of various celestial objects. Celestial objects in space (stars, galaxies, etc.) also experience a Doppler effect on their emitted electromagnetic radiation called redshift. The Doppler effect is a well-known physical phenomenon which results in a change of a wave’s frequency or wavelength due to the motion of its source. ![]()
