Best Answer

The EM spectrum includes visible light. If an object moving very fast comes toward a reference point, the visible light radiating off it/reflecting off it gets "squashed": the wavelengths become shorter. This makes the visible light accquire a blue tinge. The opposite happens for an object heading away, and it looks more red.

How is the blue shift related to the lifecycle of a star?

Not at all. "Blue shift" refers to a shift of features in the star's spectrum toward shorter wavelengths, for stars that are moving toward us. It has nothing at all to do with the composition or properties of the star itself.


The range of electromagnetic waves placed in a certain order is called the?

Well there is the Electromagnetic (EM) spectrum. Visible light is the light that we can see and they are red, orange, yellow, green, blue, indigo, and violet. On the EM spectrum there is radio/ TV, microwaves, infrared, ultraviolet (UV), xrays,and gamma rays.


What does blue and green light make?

Blue and Green make the color Red in the Electromagnetic (EM) Spectrum.


How are Doppler blue and red shift different?

A blue shift is observed in the spectrum from an object approaching the observer whereas a red shift is observed for a receding object.


As you move from the blue region of the electromagnetic spectrum to the red region of the electromagnetic spectrumwhat happens to the frequency of the light?

it gets higher.


What happens to the wavelengths of light As you move from the blue region of the electromagnetic spectrum to the red region of the electromagnetic spectrum?

It Increases. Red light has a wave length of about, 620-750 nm. Blue light a wave length of about 450-475 nm

Is white light a single color- Does it have a place in the electromagnetic spectrum like red and blue do?

white light is not a single color..it is made up of 7 different colors which include red and blue and yes it is there in the electromagnetic spectrum between ultraviolet and infrared radiation


As you move from the blue region of the electromagnetic spectrum to the red region of the electromagnetic spectrum what happens to the frequency of the light?

colour blue ------> red frequency drops, wavelength increases, because speed remains constant and speed=frequency*wavelength


What are differences in colors of moving objects in space that are approaching and moving objects that are moving away?

Objects moving toward you will have a blue shift in their spectrum and objects moving away from you will have a red shift in their spectrum. This is known as a doppler shift.


What colors make up the electromagnetic spectrum?
