In red shift how visible light from an object is shifted towards the red end of the spectrum?

Answer 1

Objects moving away from the observer (that's us) at near the speed of light are red shifted because the frequency of the light is reduced so that the color changes. Blue is a higher frequency than Red. So if an object is moving fast enough the Blue light from the object will look Red.

Answer 2

It is the light equivalent of the doppler shift. If a train is passing you while sounding its whistle, the pitch of the whistle will be higher as the train approaches you, and lower after it passes and is going away from you. Light behaves similarly; if a luminous object is approaching you, the frequency ("pitch") of the light will increase. since blue light is higher in frequency, the shift of the light is toward the blue ("blue shift"); if the object is moving away from you, the light is shifted to a lower frequency, which is toward the red. The observed lighr from distant galaxies exhibits a shift toward the red, implying that those galaxies are moving away from us. However, some galaxies (closer ones) are actually moving toward us and exhibit a blue shift.

Answer 3

First imagine the wave traveling towards you, all wibbly and "W" shaped. :)

Now, if you travel towads the wave's source you will be receiving the wave faster, you'll hit the peaks of the wave more frequently - ie. from your perspective the wave has a *higher frequency*. In this case, it is shifting towards the blue, higher frequency, end.

Stars of course are moving away from us (due to expansion of the universe). This means that we are receiving the wave slightly slower, the peaks are hitting us less frequently, and so the light wave has shifted to a lower frequency - the red end of the spectrum.

This is what we mean by redshift.

Answer 4

Its shifting remote from us additionally widespread by way of fact the crimson shift, it is led to by using the favored doppler result. From the wiki In physics and astronomy, redshift happens while the electromagnetic radiation, frequently seen easy, this is emitted from or meditated off of an merchandise is shifted in direction of the crimson end of the electromagnetic spectrum. extra frequently, redshift is defined as an boost interior the wavelength of electromagnetic radiation won by using a detector in comparison with the wavelength emitted by using the source. This boost in wavelength corresponds to a cut back interior the frequency of the electromagnetic radiation. Conversely, a cut back in wavelength is declared as blue shift. Any boost in wavelength is declared as "redshift", in spite of if it happens in electromagnetic radiation of non-optical wavelengths, including gamma rays, x-rays and ultraviolet. This nomenclature may be complicated on the grounds that, at wavelengths longer than crimson (e.g., infrared, microwaves, and radio waves), redshifts shift the radiation remote from the crimson wavelengths. A redshift can take place while a easy source strikes remote from an observer, equivalent to the Doppler shift that variations the frequency of sound waves. in spite of if watching such redshifts, or complementary blue shifts, has quite a few terrestrial purposes (e.g., Doppler radar and radar weapons),[a million] spectroscopic astrophysics makes use of Doppler redshifts to confirm the flow of distant astronomical gadgets.[2] This phenomenon became first predicted and stated interior the nineteenth century as scientists began to contemplate the dynamical implications of the wave-nature of sunshine.

Answer 5

Altered harmonic vibration through molecule interaction in the visible spectrum.

it has everything to do with angles of refraction and wave harmonics created by light quanta particle streams, as we can perceive it through the design of our eyes, and you could think of it in a similar manor to how we understand sound by design, if you tap on a tuning fork, you will hear a sharp pitch with your ear, and over time the sound harmonics varies through altered wave lengths, and if you could assign multiple colors with in a variance ratio to the multiple wave length which you hear, then you would observe the tuning fork cycle through all of the visible color spectrum's of light.
