What does the increase in wavelength of light from a galaxy mean?
This is usually expressed, equivalently, as a reduction in frequency. It means that the galaxy moves away from us. For more information, you may want to read about redshift.
When a star or galaxy moves quickly toward an observer the light it emits will appear?
It will be "blue-shifted". That is, the wavelength of the light will appear to be shorter and so more blue.
How far is Andromeda galaxy from the Sun?
About 2.5 million light years from Earth, but since the Earth and Sun are only 8 light minutes apart, there isn't that much of a difference in how far the Andromeda Galaxy is from the Sun or Earth. So the Andromeda Galaxy is about 2.5 million light years from the Sun and Earth.
How many light years from the milky galaxy and the Andromeda galaxy?
The Andromeda Galaxy is at a distance of about 2.5 million light-years from Earth; or from the Milky Way.
How light years is the seyfert galaxy from earth?
It is not correct to talk about "the" Seyfert galaxy - Seyfert galaxies are a type of galaxy.

Does resolution decreases when the wavelength of the illumitating light decreases?
No the resolution would increase as wavelength of the illuminating light decreases.
If wavelength of light is 104 of radii of earth than why it will penetrate deeper in sea?
if wavelength of light is of order of radii of earth then why it will penetrate deeper in sea?
What galaxy is 19 million light years from Earth?
The Blackeye Galaxy (M64 galaxy).
What galaxy is 12 million light years from Earth?
The Cigar Galaxy (M82 galaxy).
How far is Andromeda galaxy from the Sun?
About 2.5 million light years from Earth, but since the Earth and Sun are only 8 light minutes apart, there isn't that much of a difference in how far the Andromeda Galaxy is from the Sun or Earth. So the Andromeda Galaxy is about 2.5 million light years from the Sun and Earth.
Does the colour of a galaxy reflect its distance away from the earth?
No, however, we can determine whether a galaxy is moving towards or away from us, by looking at the shift in its spectrographic analysis. There are "red shifts" and "blue shifts" in spectrographic results. "Blue shifts" indicate that a galaxy is moving towards us, because the wavelength of the light emitted by the galaxy is compressed, causing it to shift to the blue end of the colour spectrum. "Red shifts" indicate that a galaxy is moving away from us, because the wavelength of the light emitted by the galaxy is being stretched towards the red end of the colour spectrum.
What is the shift in the light of a galaxy toward the red wavelength called?
This phenomenon is called red shift.
What galaxies are 12 million light years from Earth?
Bode's Galaxy (M81 galaxy) and the Cigar Galaxy (M82 galaxy).
How many light years from the milky galaxy and the Andromeda galaxy?
The Andromeda Galaxy is at a distance of about 2.5 million light-years from Earth; or from the Milky Way.
Where is planet earth in the milky way galaxy?
our galaxy contains between 200- to 400-billion stars arranged in a giant disc shape. The diameter is 100,000 light years with an average thickness of 10,000 light years. The Earth is located about 28,000 light years from the center of the Milky Way.
