Alight wave moves from a medium where particles of matter are closely packed to a medium made of very little matter. how do you expect the light wave to travel differently?

the light will change wavelength and lose energy.

the wavelength will change along with the frequency.

the wave will move faster, increasing its speed.

Nitrogen (n2) undergoes an internally reversible process from 6 bar, 247°c during which pν1.2 = constant. the initial volume is 0.1 m3 and the work for the process is 121.14 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/s. show the process on a t-s diagram.
