What cause changes in the light coming from distant stars and galaxies?
The apparent redshift is caused by the Doppler Effect; the frequency of waves is increased by an approaching source and decreased by a leaving source. Since the fgrequencies we see from stars are slightly lower than they should be, we know that the stars and other objects are moving away. The Doppler Effect causes changes of light emanating from distant stars and galaxies.
What causes changes in the light coming form distant stars and galaxies?
Changes in the light from distant stars and galaxies can be caused by several factors, including intrinsic variations in the stars themselves, such as pulsations or eruptions, which can alter their brightness. Additionally, gravitational lensing can bend and magnify light from distant objects due to the presence of massive foreground objects. Cosmic events like supernovae also lead to dramatic changes in brightness. Lastly, the redshift effect, caused by the expansion of the universe, can alter the observed wavelength of light from distant galaxies.
Are stars reflected light?
No. Stars emit light.
Does light travel to the stars?
light travels from the stars (arrtard
How stars acquires light?
Stars emit light they do not acquire it
Do stars reflect light from moon or sun?
Stars do not reflect light from the Moon or the Sun. Stars emit their own light due to nuclear fusion reactions happening in their cores. The light we see from stars is the result of this emission, not reflection.
Does the sun give the stars light?
No, the sun gives light to the moon, but not the stars. the stars give their own light.
How do stars such as the sun produce light?
Burns and the sun makes stars light up as the light is reflected........
What do you call the light from the stars?
Light.
How do planets and stars send light to us?
Planets reflect light from the sun. Stars emit their own light.
Are the stars measured in light years?
Stars are not measured in light years. The distance between them is.
Are stars twinkling?
The light passes through our atmosphere; this atmosphere changes all the time. Small changes in density will change the index of refraction, and change the direction of the light; that's what we see as twinkling.
