Q No-2: (a) Develop an expression for the de Broglie wavelength of a particle in terms of its K.E. and rest mass. Q No-2: (b) Differenciate between different types of X-rays on the basis of their source spectrum etc. Q No-2: (c) If the wavelength of the first line of Lyman series of hydrogen is 1215 angstrom find the wavelength of second line of Lyman series.
