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.

What does the term blue shift refer to?
Blue shift refers to the phenomenon where the light or other electromagnetic radiation from an object shifts towards shorter wavelengths, often resulting in a blue shift in the spectrum. This can occur when an object is moving towards an observer, causing a compression of the waves and a shift towards the blue end of the spectrum.
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.
Which band of the electromagnetic spectrum has a wavelength in between infrared and uv?
The band of the electromagnetic spectrum that has a wavelength between infrared and ultraviolet is the visible light spectrum. This is the portion of the electromagnetic spectrum that is visible to the human eye and includes colors such as red, green, and blue.
What does a shift toward the blue end of the spectrum mean?
A shift toward the blue end of the spectrum means that the light being observed has a higher frequency and shorter wavelength compared to light at the red end of the spectrum. This shift is known as "blue shift" and is commonly seen in scenarios where the light source is moving closer to the observer, such as with objects moving towards Earth in the universe.
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.
What does blue and green light make?
Blue and Green make the color Red in the Electromagnetic (EM) Spectrum.
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.
As you move from the blue region of the electromagnetic spectrum to the red region of the electromagnetic spectrum what happens to the wavelengths of the light?
It Increases. Red light has a wave length of about, 620-750 nm. Blue light a wave length of about 450-475 nm
What is the opposite of the red shift?
The opposite of the red shift is the purple shift.
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
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 is white light and where is it found on the electromagnetic spectrum?
White light is a combination of all the colors in the visible spectrum, which includes red, orange, yellow, green, blue, and violet. It is found in the middle of the electromagnetic spectrum, between infrared and ultraviolet light.
