Figure shows a ray of light as it travels from medium a to medium b. the refractive index of medium b relative to medium a is ?

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

Agas contained within a piston-cylinder assembly undergoes three processes in series: process 12: compression with pv= constant from 1 bar and 1 liter to 4 bar. process 23: constant pressure expansion to 1 liter. process 31: constant volume calculate the pressure and volume at each state, and sketch the processes on a p-vdiagram labeled with pressure and volume values at each numbered stat
