What is waves
100
a wave that moves the medium in a Direct perpendicular (at a right angle) to the direction in which The waves travel
What is Transverse waves
100
he duration of one complete cycle of a wave or oscillation: the reciprical of the frequency
What is Period
100
the bouncing back of an object or a wave when it hits a surface through which it cannot pass
What is reflection
100
the maximum distance the particles of a medium move away from their rest positions as a wave passes through the medium
