NEET Physics Question - Modern Physics

Assertion (A): Wavelength of continuous X-ray varies from a minimum value to infinity.

Reason (R): Continuous X-rays are emitted due to transition of electron from higher to lower energy level.

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:

Continuous X-rays (Bremsstrahlung) are produced when high-speed electrons are decelerated in the electric field of atomic nuclei.

They have a continuous spectrum with a minimum wavelength. Characteristic X-rays, not continuous ones, are due to electron transitions between energy levels.
