NEET Physics Question - Wave Optics

Assertion (A): Light is diffracted around the edges of obstacles and it bend such a way which is not easily observed.

Reason (R): The wavelength of light is very small.

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

Both (A) & (R) are true but the (R) is not the correct explanation of the (A)

(A) is true but (R) is false

Both (A) and (R) are false

Solution:

Diffraction is noticeable when the wavelength is comparable to the obstacle size. Light has a very small wavelength \( approx 400-700 \text{ nm}\), making its diffraction around macroscopic objects hard to observe. Hence, both A and R are true, and R is the correct explanation for A.
