Assertion: Ultrasonic is the acoustic analogue of ultraviolet...

Assertion: Ultrasonic is the acoustic analogue of ultraviolet radiation. Reason : Ultraviolet rays do not produce visual sensations while ultrasonic waves are not heard by the human ear.

Options

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

Correct answer

A. If both Assertion and Reason are correct and Reason is the correct explanation of Assertion.

Step-by-step solution

Utrasound (>20 KHz) is inaudible to humans, just as ultraviolet radiation is invisible. Hence ultrasonic is the acoustic analogue of ultraviolet. Both Assertion and Reason are true, and Reason correctly explains Assertion.
