The Universe Review

Front

What happens to the wavelength and frequency of light during redshift?

Back

The wavelength increases, and frequency decreases.

Front

How does frequency change as an object approaches and then moves away from you?

Back

The frequency increases as it comes toward you then decreases as it passes.

Front

What is the primary function of a satellite?

Back

To orbit the Earth and transmit various types of data.

Front

What is Doppler shift?

Back

The wavelength in front of the object gets shorter and behind gets longer.

Front

How does gravity affect nebulas in the formation of solar systems?

Back

Gravity causes nebulas to spin and flatten, forming an accretion disk that creates stars and planets.

Front

What is redshift in astronomy?

Back

Redshift is the phenomenon where light from an object moving away from an observer is shifted to longer wavelengths.

Front

What is blueshift in astronomy?

Back

Blueshift is the phenomenon where light from an object moving toward an observer is shifted to shorter wavelengths.

Front

What is the significance of the Doppler effect in astronomy?

Back

The Doppler effect helps astronomers determine whether an object in space is moving toward or away from Earth.

Front

What role do satellites play in modern technology?

Back

Satellites are used for communication, weather monitoring, navigation, and scientific research.

Front

What is an accretion disk?

Back

An accretion disk is a structure formed by diffused material in orbital motion around a central body, often seen in the formation of stars and planets.
