CLASS 12 PHYSICS CHAPTER 11-DUAL NATURE OF RADIATION AND MATTER

Question1. Find the (a) maximum frequency, and (b) minimum wavelength of X-rays produced by 30 kV electrons. Solution :Potential of the electrons, V = 30 kV = 3 × 104 V Hence, energy of the electrons, E = 3 × 104 eV Where, e = Charge on an electron = 1.6 × 10−19 C (a)Maximum frequency produced by …
