NEET Physics Question - Modern Physics

Assertion (A): Penetration power of hard X-ray is more than that of soft X-ray.

Reason (R): Hard X-ray is used for engineering purpose while soft X-ray is used for medical purpose.

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:

Hard X-rays have shorter wavelengths and higher energy, leading to greater penetration power than soft X-rays. While both the assertion and reason are factually correct regarding X-ray properties and applications, the reason describes their uses, not the physical explanation for their differing penetration power.
