### Waves

Ginny Jameson

This puzzle is to help you with the basic vocab of the wave unit. There will be a lot of basic, and new vocabulary. There will also be some fumuals on there.

Across
2.a wave is a component frequency of the signal that is an integer multiple of the fundamental frequency
4.time required for one wave to pass
9.The bending or spreading of a wave as it passes an obstruction.
11.a technique for determining the distance to an object under water
16.f time lambda
17.When two waves tend to do opposite things to medium, the total effect builds up. This is know as destructive interference.
18.a material through which a wave travels
19.a wave that appears to stay in one place and does not seem to move through the
20.an area of a longitudinal wave where the particles of the medium are close together
22.the response of a standing wave to another wave of the same frequency, with dramatic
24.the maximum height of a wave
26.When two or more waves share the same space at the same time These waves both act independently on the medium
28.the lowest point of a transverse wave
30.the highest point of a transverse wave
32.the rate at which a wave’s energy flows through a given unit of area
33.The bending of a wave as it passes the boundary between two media.
Down
1.a physical response to the intensity of sound, modified by physical factors
3.a wave that travels along a surface separating two media
5.a change in sound frequency caused by motion of the sound source, motion of the
6.When two waves tend to do same thing to medium, the total effect builds up. This is know as constructive interference.
7.a wave that causes the medium to vibrate at right angles to the direction in which
8.a longitudinal wave consisting of compressions and rarefactions , which travels through
10.the distance between a point on a wave and the same point on the next wave
12.Bouncing back of a wave as it strikes a boundary
13.a wave in which the vibration of the medium is parallel to the direction the wave
14.a disturbance in matter that carries energy from one place to another
15.any motion that repeats at regular time intervals
21.an area of a longitudinal wave where the particles of the medium are spread out
23.the number of complete waves that pass per second
24.a point of maximum displacement midway between two nodes in a standing wave
25.a unit that compares the intensities of different sounds
27.the frequency of a sound as a listener perceives it
29.unit used to measure frequency of a wave
31.a point on a standing wave with no displacement from rest
