Continuous X-ray Production – Rankers Physics

Atomic Structure: Practice Problem & Solution

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 Explained:

To solve this problem, we apply the core principles of Atomic Structure. Understanding the underlying formula is key to arriving at the correct answer below:

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.
