The peaks represent characteristic xrays. Their appearance depends on the target material. KB 30 40 50 60 70 80 л (pm) 90 The continuous curve represents bremsstrahlung. The shortest wavelength depends on the accelerating voltage. Figure 41.22 The x-ray spec- trum of a metal target. The data shown were obtained when 37-keV electrons bombarded a molybde- num target. Intensity
In x-ray production, electrons are accelerated through a high voltage and then decelerated by striking a target. (a) To make possible the production of x-rays of wavelength λ, what is the minimum potential difference ΔV through which the electrons must be accelerated? (b) State in words how the required potential difference depends on the wavelength. (c) Explain whether your result predicts the correct minimum wavelength as shown. (d) Does the relationship from part (a) apply to other kinds of
