Text Solution

Verified by Experts

The correct Answer is:
B
A quasar is a very big source of radio waves and its size is very small as compared to the size of a galaxy. A radio galaxy emits radio waves which lie in the range ` 10^(30)` to ` 10^(38)` watt. A quasar emits radio waves which lie in the range of ` 10^(37)` to ` 10^(38)` watt.
