A longitudinal wave moves energy that is
to the direction of the wave's movement.

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.

Acalorimeter uses the principle that thermal energy flows from hotter material to colder material until both reach the same

Does heating a metal wire increase or decrease its electrical resistance? why?
