Problem 2
(13%) Problem 2: a copper plate In an evacuated tube electrons produce X-rays by accelerating from rest through a voltage of 0.39 kV and striking D à Nonrelativistically, whar would be the maximum speed of these electrons, in meters per second? Grade Summary
An x-ray tube operated at DC pd of 40KV produces heat at the target at the rate of 720W. assuming 0.5% of the energy of the incident electrons is converted into x radiation. calculate: (1) the number of electrons persecond stricking the target (2) the velocity of the incident electrons. (Assuming charge to mass ratio of electron to be1.8*10^11C/Kg)

The tube in a medical research X-ray unit uses lead (Z=82) as it's target. 1) Use the Bohr model to estimate the minimum kinetic energy electrons must have to in order for Kα X-rays to just appear in the X-ray spectrum of the tube. Ee = 2) Assuming the electrons are accelerated from rest through a voltage, V, what is the minimum voltage necessary to produce the Kα X-rays?
When the accelerating voltage in an X-ray tube is doubled, the wavelength of the X-rays is a. Increased to twice the original value b. Is increased to four times the original value c. Decreased to one-half the original value d. Decreased to one-forth its original value Explain
What is the accelerating voltage of an x-ray tube that produces a spectrum of x rays, with the shortest wavelength being j 0.020 nm?
an electron, traveling at a speed of 5.8e6 m/s, strikes the target of an X-ray tube. Upon impact, the electron decelerates to one third of its original speed, with an x-ray photon being emitted in the process. what is the wavelength of the photon?
a) What is the minimum potential difference between the filament and the target of an X-ray tube if the tube is to accelerate electrons to produce X-rays with a wavelength of 0.477 nm? b) What is the shortest wavelength produced in an X-ray tube operated at 28.0 kV?
