With what maximum kinetic energy will electrons be ejected when this metal is exposed to light with a wavelength of 285 nm?.

What is the relationship between the wavelength of a wave and it's energy?

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
