Professor i have a note im in radiology field and your explanation is Very Clear and Attractive But there is small one thing that if you increase the intensity you only decrease the SNR of the radiograph i mean if u decrease the intensity your image get noisy since in the center there will be one third of the intensity and will be photons starvations also the one control the darking of the image is kvp and its actually the more u increase it ruins contrast make it more burned out the film I have very long explanation for that I worked at nuclear medicine before and Computed tomography also mri so I may would like to see u do videos about them especially by a professor from Cambridge

Yes, that's right! Thanks for sharing some insight on intensity. Too high or low intensity is not ideal. Also, we are not professors from Cambridge 😉 just Pre-University lecturers

Miss, have you made a vid about how to calculate the minimum wavelength of X-rays produced from accelerating p.d? This is from the new 2022 Syllabus.

Max Kinetic energy of electron = work done by electron = eV = h f(max) = hc/lambda(min).

We know that energy of an electron that is made to accelerate with a potential different V is= eV and we also know that energy of photon= hc/lambda. Now if we assume that the incoming electronic transfers all its energy to the x ray photon, then putting the two equations together we get lambda= hc/eV and this way we get the min lambda

Miss intensity of X-ray is not mentioned in new syllabus so does it mean it is not included . (intensity of X-ray is mentioned in Old 2021 syllabus )
