Red Shift

Front

What is Red Shift?

Back

Red Shift is the phenomenon where light from an object moving away from an observer is shifted to longer wavelengths, making it appear redder.

Front

What does it indicate when a galaxy is moving away from us?

Back

It indicates that the universe is expanding, as observed through the red shift of light from distant galaxies.

Front

In red shift, how do the wavelengths of light change?

Back

The wavelengths of light increase, moving towards the red end of the spectrum.

Front

What is the opposite of red shift?

Back

The opposite of red shift is blue shift, which occurs when an object is moving towards the observer, causing the light to shift to shorter wavelengths.

Front

What color do galaxies appear in red shift?

Back

Galaxies appear red in color due to the red shift effect.

Front

How does red shift support the Big Bang theory?

Back

Red shift provides evidence that the universe is expanding, which supports the Big Bang theory of the origin of the universe.

Front

What is the significance of measuring red shift in astronomy?

Back

Measuring red shift helps astronomers determine the speed and direction of galaxies, as well as the expansion rate of the universe.

Front

What type of wave has the highest frequency?

Back

Gamma rays have the highest frequency among electromagnetic waves.

Front

What happens to the frequency of light in red shift?

Back

The frequency of light decreases as the object moves away, resulting in a red shift.

Front

What is blueshift?

Back

Blueshift is the phenomenon where light from an object moving towards an observer is shifted to shorter wavelengths, making it appear bluer.
