Question

Assertion : Out of Infrared and radio waves, the radio waves show more diffraction effect. Reason (R): Radio waves have greater frequency than infrared waves.

• A. If both Assertion and Reason (R) are true and Reason (R) is the correct explanation of Assertion .
• B. If both Assertion and Reason (R) are true but Reason (R) is not the correct explanation of Assertion .
• C. If Assertion is true but Reason (R) is false.
• D. If both Assertion and Reason (R) are false.

Hint:

Radio waves show more diffraction effects because of their longer wavelengths, not due to their frequency.

Answer 1

The Correct Option is C

Step 1: Analyzing the Assertion. Radio waves have a longer wavelength than infrared waves, which makes them more susceptible to diffraction. Therefore, Assertion is true.

Step 2: Analyzing the Reason. Radio waves have a lower frequency than infrared waves, not a greater frequency. Hence, Reason (R) is false.

Step 3: Conclusion. Thus, the correct answer is if Assertion is true but Reason (R) is false.
