Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Macroscopic objects in our daily life do not show wave-like properties. Reason (R): The wavelengths associated with macroscopic objects are extremely short because of their large mass. In the light of the above statements, choose the correct answer from the options given below:

  1. Both (A) and (R) are true and (R) is the correct explanation of (A).
  2. Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
  3. (A) is true but (R) is false.
  4. (A) is false but (R) is true.

Correct answer · Option 1

Both (A) and (R) are true and (R) is the correct explanation of (A).

Explanation

According to de Broglie equation \( \lambda = \frac{h}{mv} \), large mass \( m \) makes \( \lambda \) too small to be detected for macroscopic objects.
