Aperiodic wave travels from one medium to another. which pair of variables are likely to change in the process?

think its the third option

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.

hope this : d

e/c, where e is its total energy

i think it would be 5
