Effect of Change of Potential difference applied to an X-Ray tube

AI Thread Summary
Increasing the potential difference applied to an X-ray tube decreases the minimum wavelength of emitted radiation, as described by the Duane-Hunt law (λ=hc/eV). The discussion raises a question about how this change affects the intensity of the emitted radiation, which remains unclear. There is an emphasis on the theoretical understanding of X-rays, with no practical application mentioned. The original poster confirmed that their inquiry is general and not related to specific lab work. Overall, the focus is on understanding the relationship between potential difference, wavelength, and intensity in X-ray emission.

I am a high school student, so I know only the basics of X-Rays.I simply know about continuous X-rays, cutoff wavelength and threshold wavelength. Now if I increase the potential applied to the X-ray tube, I am certain that the minimum wavelength of emitted radiation decreases. (I say this using λ=hc/eV, which is the Duane-Hunt law)

I am unsure about the intensity of emitted radiation. Does that change?

Is this a general question, or are you working with X-rays in the lab? X-ray safety is an important consideration when working with lab setups.

As I said, I am in high school. There is no practical use of X-Rays. It is just the theoretical part. Actually, my textbook had a multiple choice question saying

"If we increase potential difference applied to an X-Ray tube, what of the following things will happen with the emitted radiation?
A. Intensity increases
B. Intensity decreases
C. Wavelength increases
D. Wavelength decreases.

Now, as I mentioned in the Original Post itself, I used the Duane-Hunt Law to mark the answer as D, which is obviously correct. Out of curiosity I wanted to know what would happen with the intensity. Since I myself did not have much knowledge regarding the issue, I decided not to put it under the homework section and just as a general question of Quantum Physics.

Do you have two threads about this? If so, I can merge them into one thread in the schoolwork forums. We do not allow cross-posting here, and we do not allow schoolwork posts ourtide of the schoolwork forums. Thanks.

No, I didn't create two threads. Just this one.
 
Thread 'Voltmeter readings for this circuit with switches'
TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
Thread 'Struggling to make relation between elastic force and height'
Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...
