A 17 keV electron is brought to rest with colliding twice with target nuclei as in Fig.40-15. (Suppose the nuclei remain stationary.) The wavelength associated with the photon emitted in the second collision is 140pm greater than that associated by the photon emitted in the first collision. (a) What is the kinetic energy of the electron (in terms of kV) after the first collision? What are (b) the wavelengthλ1 (in terms of pm) and (c) energy E1 (in terms of keV) associated by the first photon? What are (d) λ2 (in terms of pm) and (e) E2 (in terms of keV) associated by the second photon?

What is the power of the laser light through one of pulses : Lasers can be utilized to drill or cut material. One such laser generates a series of high-intensity pulses rather than a continuous beam of light. All pulse contains 0.500 J of energy and lasts 10 nanoseconds. The laser fires ten pulses per second.
