The increase in wavelength of light due to the expansion of space is known as redshift. As the universe expands, light traveling through space stretches, resulting in longer wavelengths. This phenomenon is most commonly observed in distant galaxies, where the light shifts toward the red end of the spectrum, indicating that these galaxies are moving away from us. Redshift is a key piece of evidence for the Big Bang theory and the ongoing expansion of the universe.

What is Doppler red shift?
Its part of science! Edit : In astronomy, the Doppler effect is the change in wavelength of light caused by movement of a light source such as a star or a whole galaxy. The term "red shift" refers to the increase in the light's wavelength from the blue to the red end of the spectrum. This happens when a light source is moving away from us. I don't want to over complicate things, but there is a similar thing called the "cosmological red shift ", but that's caused by the expansion of space itself.
How does a red shift indicate that the universe is expanding?
nice question! actually when a wave approaches an observer the wave length of the wave decrease and as it move far from us its wavelength increase. it is quiet difficult to understand so use your imagination. as the wavelenght increase the spectrum will be shifted toward red spectrum and thus called red shift. when Edward Hubble studies spectrum of different star he noticed that because of some color spectrum were missing, other spectrum got shifted to ward red. it it moved toward red then that mean that wavelength was increasing and if wavelength increases then that means light moves away from us and thus he concluded that each and every star and galaxy was moving away from each other
How far could you travel in space before you come to the end?
Space does not have an "end" like a physical boundary. It is infinite and expanding. As of now, the observable universe is about 93 billion light-years in diameter, but there is no known edge to space.
What does the red shift measure?
Redshift measure the recession speed of stars and galaxies. These speeds are proportional to distance--the farther a star or galaxy is from a given location in space, the faster that entity is moving away from that location. This proportionality is given as Hubble's Law. In general, everything is moving away from everything else, and the furthe away, the faster the acceleration (local movements not included). Dick
Is the sun yellow because of light radiates from it?
Yes, the sun appears yellow to us on Earth because its light is scattered by the Earth's atmosphere, causing shorter-wavelength light (blue and violet) to be dispersed more than longer-wavelength light (yellow, orange, and red). In space, the sun emits light across a spectrum of colors, with the majority being in the visible range.
What happens to the energy that light gains from a Gravity Assist when passing by a mass in space since light cannot increase in speed?
Light cannot increase its speed, but it can increase its energy. Doing so will increase its frequency, or equivalently shorten its wavelength. It will thus be blue shifted.
How is the universe expanding even if atom can't be created?
It is space that is expanding. The amount of matter doesn't necessarily increase. This means that the average density of the Universe is decreasing.It is space that is expanding.

How does the expansion of the universe create redshifts?
As the universe expands, the space between galaxies also expands, causing their light to stretch out as it travels through this expanding space. This stretching of light waves results in redshift, where the wavelength of light increases, shifting it towards the red end of the spectrum.
Is the speed of light in space varies with wavelength?
No, it does not.
What is guided wavelength?
Guided wavelength, also known as effective wavelength, is the wavelength of light in a medium with a refractive index different from that in free space. It is the wavelength at which light travels in a waveguide or optical fiber, taking into account the refractive index of the medium. It plays a crucial role in determining the properties and behavior of light in these structures.
What is the wavelength of a 300MHZ signal in free space?
The wavelength of a 300MHz signal in free space can be calculated using the formula: wavelength = speed of light / frequency. Given that the speed of light is approximately 3 x 10^8 meters per second, the wavelength of a 300MHz signal would be approximately 1 meter.
The wavelength of electromagnetic radiation is inversely proportional to its?
Frequency. f=c/l Where, f=Frequency, l=Wavelength and c=Velocity of light in free space.
What is the ancwer to this A company is expanding its building area from 20000 square feet to 24400 square feet. What is the percentage increase of the area of the building space?
It is a 22% increase
How is the space growing faster than its keyword?
The universe is expanding at a faster rate than the speed of light.

What is the wavelength of a 900 MHz signal in free space?
The wavelength of a 900 MHz signal in free space is approximately 0.333 meters. This can be calculated using the formula: wavelength = speed of light / frequency, where the speed of light is 3 x 10^8 meters per second.
What is the wavelength when the frequency is 900 MHz?
The wavelength can be calculated using the formula: wavelength = speed of light / frequency. At a frequency of 900 MHz (900 x 10^6 Hz), the wavelength would be approximately 0.333 meters (333 mm) in free space.
