(a) An X-ray tube produces a continuous spectrum of radiation with its shorts wavelength end ate`0.45 Å`. What is the maximum energy of the photon in the radiation? (b) From your answer to (a) , guess what order of accelerating voltage (for electrons) is required in such a tube?

Consider the function f(x)={(1-x,x 0):} Draw a rough sketch of f(x) . What is your inference from the graph about its continuity. Verify your answer using limits.

When an electron in an excited state of Mo atom falls from L to K shell an x-ray is emitted. These x-rays are diffracted at an angle of 7.75^(@) by planes with a separationof 2.64A^(@) .What is the difference in energy between K-shell and L-shell in Mo. Assuming a first order dirffraction ? (sin 7.75^(@)=0.1349)
