I solved this Biophysics problem myself.

But obviously there are a lot of places that are wrong.

Let the experts see what's right and what's wrong and explain to me what's the right answer!

What is the X-ray absorption process in which the energy of an X-ray photon is partially given to an electron and the photon scatters with the rest of the energy? * O Pair production O Stimulated Emission a? Compton effect O Photoelectric effect "Calculate the wavelength of a microwave with the frequency 2700 Mhz. " Your answer 2700mhz?? ""Electromagnetic waves are classified using what measurement? * O frequency color length c ? energy "What is the height in meters of a person who is 7 feet 2.0 inches tall? * Your answer 7 feet 2.0 inches?? Which of the following pr is not responsible for the absorption of X-rays? * O Pair production. O Compton effect c? O Photoelectric effect. Spontaneous emission. O No answer. Energy of an X-ray photon is partially given to an electron and the photon scatters with the rest of the energy during the Compton effect. At what collision angle the energy given to the electron is maximum? * 90 degrees 180 degrees 120 degrees b? 360 degrees O No answer What is the minimal energy of an X-ray photon needed for the pair production? * O 1.02 Mev O 1.02 J 0.51 Mev c? O 2.04 Mev O No answer. Which of the following statements is false? * O frequency of a radio wave is higher than frequency of an X-ray wavelength of a radio wave is longer than the wavelength of an X-rays d? the range wavelength for a visible light is 400-750 nm, approximately O frequency of a visible light is higher than the frequency of radio waves No answer 9. Which of the following statements is false? * population inversion is needed for light amplification to occur O spontane te a highly intensive laser light e ? O stimulate erent monochromatic light O stimulated absorption is needed to create a layer excited electrons O No answer 10. 3*10 8 X-ray photons enter a 3-cm thick material. What will be the number of X-ray photons after passing through the layer if the attenuator coefficient of the material is given as mu = 1.63 1/cm. * 2.25*1016 O No answer. a? O 3.5*106 16.35*106 O 29.3*1046 What is the attenuator coefficient of a certain material if we know that 3 cm of the material absorbs 65% of X-rays? * 0.1914 1/cm O 0.35 1/cm 0.232 1/cm O No answer. 0.1436 1/cm 12. An electron releases from n = 3 state to n = 2 state. What is the frequency of a photon emitted in this transition? * 6.626*10"(-34) J/S 5.46*104(13) 1/s O No answer c ? -3.0278*104(-19) 1/s 4.57*10*(14) 1/s 13. An X-ray photon with an initial wavelength lambda0 = 5*10^(-10) m hits an electron and scatters out. It changes its direction by an angle of Phi = 60 degree. Find the wavelength of the scattered photon. Hint: sin(30 degrees) = 0.5. * O No answer 5.012*104(-10) m d? 0.005 mm 50.07*10"(-11) m 5.005*10*(-13) m
