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.
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.
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.
Blue and Green make the color Red in the Electromagnetic (EM) Spectrum.
A blue shift is observed in the spectrum from an object approaching the observer whereas a red shift is observed for a receding object.
it gets higher.
It Increases. Red light has a wave length of about, 620-750 nm. Blue light a wave length of about 450-475 nm

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
colour blue ------> red frequency drops, wavelength increases, because speed remains constant and speed=frequency*wavelength
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.
red orange yellow green blue indigo violet :)
Chlorophyll absorbs the blue-violet prtion of the electromagnetic spectrum and reflects green
