Question
Chapter 17, Problem 1RQ
To determine
The relation between active galaxies and radio galaxies.
Expert Solution & Answer
Answer to Problem 1RQ
The radio galaxies are bright at radio wavelength and active galaxies emit all the different wavelengths.
Explanation of Solution
The active galaxies are the galaxies those emitting energy at different wavelengths. These are found after the telescopes probe into its orbits.
Radio galaxies were discovered during the late 1950’s using the large size radio telescopes by the astronomers
The radio galaxies are characterized by the virtue of their brightness at radio wavelength.
Conclusion:
Therefore, the radio galaxies are bright at radio wavelength and active galaxies emit all the different wavelengths.
