1. waves transport ( energy / mass ) from one place to another.

2. transverse waves:

a) matter moves ( up & down / left& right ) when the energy moves from left to right.

b) a guitar string has a length of 0.90 m. when you pluck it, it plays a “c” that has a frequency of 256 hz. how fast is the waves moving back and fourth along the string?
(choose one of the equations from the box at the top of the page to solve this problem.)

sound waves:
a) are ( mechanical / electromagnetic ) therefore must travel through a medium.
b) aee ( transverse / pressure ) waves where the matter moves in the same direction as the wave energy.
c) in a train track made of solid steel, sound waves travel extremely fast— about 6,000 m/s. if a train’s vibration travels for 3 seconds, how far will it move? (choose one of the equations from the box at the top of the page to solve this problem.)
d) sound waves travel quickest through ( solids / liquids / gasses) and slowest through ( solids / liquids / gasses).
