Assertion : Quasar emits radiowaves more than radio galaxy. Reason...

Assertion : Quasar emits radiowaves more than radio galaxy. Reason : Quasar has very small size.

Options

  1. AIf both the assertion and reason are true and reason is a correct explanation of the assertion.
  2. BIf both assertion and reason are true but assertion is not a correct explanation of the assertion.
  3. CIf the assertion is true but the reason is false.
  4. DIf both assertion and reason are false.

Correct answer

B. If both assertion and reason are true but assertion is not a correct explanation of the assertion.

Step-by-step solution

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 103010^{30} to 103810^{38} watt. A quasar emits radio waves which lie in the range of 103710^{37} to 103810^{38} watt.
