A beam of light strikes a sheet of glass at an angle of 56.6° with the normal in air. You observe that red light makes an angle of 38.4° with the normal in the glass, while violet light makes a 36.4° degree angle.
1.What are the indexes of refraction of this glass for these colors of light?

2.What are the speeds of red and violet light in the glass?

What type of light does this light bulb produce most (i.e. at what wavelength does the spectrum have maximum intensity)?

Steam is generated in a boiler of a cogeneration plant at 10 mpa and 450°c at a steady rate of 5 kg/s. in normal operation, steam expands in a turbine to a pressure of 0.5 mpa and is then routed to the process heater, where it supplies the process heat. steam leaves the process heater as a saturated liquid and is pumped to the boiler pressure. in this mode, no steam passes through a condenser, which operates at 20 kpa. (a) determine the power produced in the turbine and the rate at which process heat is supplied in this mode. (b) determine the power produced in the turbine and the rate of process heat supplied if only 60 percent of the steam is routed to the process heater and the remainder is expanded to the condenser pressure.
