If a Michelson interferometer has a mirror velocity of 1.00 cm/s, what will be the frequency at the transducer due light leaving the source at frequencies of
(a) 4.8×1013 Hz?
(b) 4.9×1013 Hz, and
(c) 5.0×1013 Hz? What are the corresponding wavenumbers of these frequencies?
5 A JFET has Na= 10 19cm -3, Nd= 10 16cm -3, a= 0.1 µm, L= 10 µm and Z= 1 mm. Assume the device is Si with an intrinsic concentration of 10 10cm -3and a relative dielectric constant of 11.8. Assume also that in saturation the square law can be use..
Hydrogen is contained in a piston-cylinder device at 14.7 psia and 15 ft3. At this state, a linear spring (F 8 x) with a spring constant of 15,000 lbf/ft is touching the piston but exerts no force on it. The cross-sectional area of the piston is 3..
