Short Answer Type
where n is Principal Quantum number. Calculate the wavelength of electromagnetic radiation emitted by hydrogen atom resulting from the transition: n = 2 to n = 1.
i) What is Compton effect ?
(ii) In Coolidge X-Ray tube (Modern X-Ray tube) how will you vary:
(1) intensity of emitted X-Rays?
(2) penetrating power of emitted X-Rays?
(i) Compton effect is the phenomenon due to which wavelength of radiation scattered by an element is slightly greater than that of the incident radiation.
(ii) Intensity of emitted x-ray is increased by increasing the current flowing through the filament.
(2) Penetrating power of X-ray is increased by increasing the p.d between cathode and anticathode.
(i) Which electronic device: a rectifier, an amplifier or an oscillator does the above circuit represent?
(ii) State where the input voltage is applied and where the output voltage is available.
(iii) Compare the output voltage of this circuit with its input voltage.
