By the formula lambda=h/p=h/under root 2meV
so lambda is inversely proportional to V. (p=2mK=2mqV=2meV)
During X-ray formation if voltage is increaseda) ...
Explanation:
When X-rays are formed, they are produced by the interaction of high-energy electrons with a target material. This process is known as X-ray emission. X-rays are electromagnetic waves with very short wavelengths and high frequencies.
When the voltage applied to the X-ray tube is increased, it affects the energy of the electrons accelerated towards the target. This increase in voltage leads to an increase in the kinetic energy of the electrons. According to the de Broglie equation, the wavelength of a particle is inversely proportional to its momentum. Therefore, when the kinetic energy of the electrons increases, their momentum also increases, resulting in a decrease in the wavelength of the X-rays produced.
Key Points:
The question asks about the effect of increasing voltage on X-ray formation. The correct answer is option 'A', which states that the minimum wavelength decreases. This means that the X-rays produced have a shorter wavelength when the voltage is increased.
To summarize:
- Increasing the voltage applied to the X-ray tube increases the kinetic energy of the electrons.
- The increased kinetic energy of the electrons leads to an increase in their momentum.
- According to the de Broglie equation, the wavelength of a particle is inversely proportional to its momentum.
- Therefore, when the momentum of the electrons increases, the wavelength of the X-rays produced decreases.
Conclusion:
The correct answer is option 'A' - When the voltage is increased during X-ray formation, the minimum wavelength of the X-rays produced decreases. This is because the increased voltage leads to an increase in the kinetic energy of the electrons, resulting in a decrease in the wavelength of the X-rays produced.
