Physics 6

Question 1

Transverse Waves

Answer 1

causes wave particles of a medium to vibrate perpendicularly to the direction of propagation (motion) of waves

Question 2

Longitudinal Waves

Answer 2

causes the particles of a medium to move parallel to the direction of the wave

Question 3

Surface Waves

Answer 3

A mixture of transverse and Longitudinal waves that travel on the surface of a medium. Especially like on ocean surfaces. they consist of both parallel and perpendicular motion.

Question 4

Period

Answer 4

T

The time it takes to get from a crest to crest or trough to trough for examples. The time it takes for the wave to repeat itself

Question 5

Travelling Wave

Answer 5

A travelling wave moves along a medium

Question 6

Wave Pulse

Answer 6

A single disturbance that travels through a medium

Question 7

Frequency

Answer 7

f

the # of complete vibrations per second, measured at one fixed point. The unit for frequencys hertz (Hz). One Hertz is one vibration per second.
