![]() Light and wave lengths from the Andromeda galaxy are Blueshifts. Scientist Edwin Hubble has been credited with further confirming the Redshift phenomenon through extensive study now known as Hubble’s Law. Told you it was complicated, however you should understand more about these shifts now. So, Redshifts are Red and Blueshifts are Blue, and this is proven by the colour of light emitted from the stars. This is happening already, and is also noticeable by the Blue tint when observing the galaxy. While stars in that galaxy may be moving away from each other in the galaxy, it is widely confirmed that our nearest neighbour is actually moving towards the Milky Way, where at some stage in the very distant future both galaxies will collide, to form a new super galaxy. So its a little complicated, because if the very widely known theory of the continued expansion of the universe, and acceleration of stars away from each other is 100% accurate, how can a Blueshift occur? Good question. ![]() This is noticeable by the Red tint in the star when observed.īlueshifts are Blue and are the opposite of Redshifts. When stars are moving away from other stars or objects at acceleration, this is a Redshift. This is shift in wave, of a Doppler Shift. When the ambulance reaches you, you can hear the true sound, and when it passes you, a different sound is made from the wave, giving a low frequency as it passes, until the wave is gone, and you cannot hear the ambulance anymore. When approaching you the noise of the siren is compressed together, giving the wave a high frequency. A good simple example of explaining the Doppler Effect would be to imagine and ambulance coming towards out with its siren on. The effect is a change in frequency of a wave of acceleration in the universe. Redshifts are based the ‘Doppler Effect’ that was named after scientist Christian Doppler who is credited with coming up with the system of explaining Redshifts as proof that the universe is forever expanding. Wavelengths expanding for a Redshift, and wave lengths reducing for a Blueshift. Its all about wavelengths for both Redshifts & Blueshifts. The picture above is a good starting point, so look at it again after you understand more about these shifts, as it will make more sense to you. These shifts are complicated things to explain, however here goes. We are really getting into the physics of things. The experimental results and theoretical predictions are quite consistent.What causes Redshifts & Blueshifts? And based on what causes them, what are they exactly? ![]() An experimental investigation has been carried out, on sheet glasses with different roughness on one side, in reflection and transmission modes. Also, the redshift and blueshift decay with increase of the scattering angle. b is the observed blue-shift wavelength is the emitted wavelength (Greek. Blue-shift wavelength equation The blue-shift equation for wavelength is: b c/(c + v b) where. With decrease of the latter intensity the blueshift reduces and turns into redshift. Knowing the velocity of the moving source of light (v s), you can use the equations c f and f c/ to convert the frequency equations to solve for wavelength. This study shows that the spectrum of the diffusely scattered light is blueshifted in the specular direction and in directions with small scattering angles only in situations with appreciable intensity of the coherently scattered light. The redshift and width shrinkage increase with decrease of the coherently scattered light intensity. In transmission mode they also depend on the refractive indices of the surrounding media. In reflection mode the amounts of the redshift and the shrinkage depend on interface roughness, incident angle, and the spectral width of the illuminating light. ![]() We show theoretically and experimentally that the spectrum of coherently scattered light from a randomly rough interface in reflection and transmission is redshifted with a shrinkage in spectral width. ![]()
