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 is the opposite of the red shift?
The opposite of the red shift is the purple shift.
Can a red shift and a blue shift exist on the same object at the same time?
No, red shift and blue shift are opposite phenomena caused by the Doppler effect. Red shift occurs when an object is moving away from the observer, while blue shift occurs when an object is moving towards the observer. It is not possible for an object to exhibit both red shift and blue shift simultaneously.
How does a red shift from a blue shift?
A red shift shows us that a object is moving away, while a blue shift shows us an object is moving toward us. Light that has been 'red shifted' has a longer wavelength when it reaches our eyes/telescopes/etc. than it had when it left the object. Light that has been 'blue shifted' now has a shorter wavelength. The reason stretching the wavelength is known as 'red shifting' is that, in the visible spectrum, red light has the longest wavelength. Blue light has a much shorter wavelength than red so when the wavelength is compressed, we call it blue shifting.
How does blue and red shift help us understand the changes of the universe?
Red shift has confirmed the expansion of universe. Both red and blue shift at the edges of the sun has confirmed the spin of sun..
Why is red light different to blue light?
The red light is lower energy than the blue light.
Does blue or red have a higher frequency?
Blue light has a higher frequency than red light. When we see different colors, we are actually perceiving different wavelengths of light - blue light has a shorter wavelength and higher frequency than red light.
Does blue light have travel at a different frequency than red light in the same medium?
Yes. Blue light has a shorter wavelength, and therefore a higher frequency, than red light.
Red light and blue light are different colors because the light that makes them up has different?
wavelengths. Red light has a longer wavelength than blue light, with red light having a wavelength around 620-750 nanometers and blue light around 450-495 nanometers. This difference in wavelength is what gives them their distinct colors.
Why are red shift and blue shift effects useful in the study of the universe?
Red shift means that other objects in the universe are moving away and blue shift means they are moving toward you. This helps to tell where these objects came from, and this knowledge helps predict where they are going to.
When a source of light approaches an observer the light appears to be than it actually is?
Blue shifted and when it is moving away it is under a red shift.
Do blue visible light and red visible light have the same wavelength?
No, blue and red visible light have different wavelengths. if you see the rainbow, blue and red can been seen on separate stripes which means they have different wavelengths.
