A stabilized He-Ne laser operates at a wavelength of λ=632.8 nm and has a bandwidth of Δν=1 kHz. The total power of the light beam is 1mW and the diameter of the beam is 1mm.
A) Determine the irradiance of the laser and the number of photons emitted per unit of time
B) What should be the temperature of a black body so that it emits the same number of photons, in the same area and in the same frequency range as the laser?
A soft x-ray used in medicine has a wavelength between 10pm to 10 nm. In medical diagnostic applications, the low energy (soft) X-rays are unwanted, since they are totally absorbed by the body, increasing the radiation dose without contributing to the image. Hence, a thin metal sheet, often of aluminum, called an X-ray filter, is usually placed over the window of the X-ray tube, absorbing the low energy part in the spectrum. This is called hardening the beam since it shifts the center of the spectrum towards higher energy (or harder) X-rays.
Calculate the Energy in Joules/photon when a wavelength of 85.5 pm takes a produces an image.
Photons (50 KeV )from an X-ray tube fall on adjacent tissues below. Knowing that the thickness of the fat and muscle layers are 4.8 mm and 7.2 mm, respectively, and that the intensity of the incident beam in the fat is Io, the percentage of the incident beam that reaches the detector located after the muscle layer is:

a) 50.4%
b) 97.2%
c) 85.8%
d) 11.7%
e) 77.1%
