Wave Properties
Waves: Waves are disturbances that transfer energy from one space
to another without transferring matter
Q&A:
………… always begin with a source of energy that causes a backand forth
OR up or down disturbance movement. (Final Exam 2021)
- Medium (Matter): A material though which a wave travels

1- Amplitude - the height of a wave, from resting position to
crest
The the amplitude, the the wave has
E=A2
2- Wavelength - distance from any point on a wave to an identical
pointon the next wave
The shorter the wavelength the more energy the wave has

3- Frequency - the number of waves produced in a given
amount of time.
a. measured in hertz (Hz) 1 Hz = 1 wave per second
Note that:
Frequency and wavelength are inversely related, whichmeans as
one decreases the other increases (and vice versa)

There are two types of waves:
1. Mechanical wave
2. Electromagnetic wave
Mechanical wave:
-Travel only through matter
-They need a medium
-Solid – liquid – gas For example: Water – air – sound
Electromagnetic wave:
-Travel through empty space (vacuum) or through matter
For example: only light
Mechanical waves have two types:
1. Transverse wave
2. Longitudinal wave

1- Transverse wave:
Waves in which the medium moves at right angles to the direction of the
wave perpendicular to the direction the wave travels
For example: water
Parts of transverse waves:
Crest: the highest point of the wave
Trough: the lowest point of the wave
1- Crest: The highest point on a transverse wave

- longitudinal wave:
- longitudinal waves: waves in which the medium moves back and forth in the same
direction as the wave parallel to the direction the wave travels
Parts of longitudinal waves:
Compression: where the particles are close together
Rarefaction: where the particles are spread apart
What is the difference between compression regions and rarefaction
region?
Compression regions where the particles of the medium are closest together
Rarefaction regions where the particles are farthest apart.

In transverse wave Wave length is distance from crest to crestor from trough
to trough
While in longitudinal waves wave length is distance between twosuccessive

Last Minute Summary:
o Waves: Waves are disturbances that transfer energy from one space to another
without transferring matter
o Amplitude - the height of a wave, from resting position to crest
the larger the amplitude, the more energy the wave has
Mathematical Equation : E=A2
o Wavelength - distance from any point on a wave to an identical point on the next
wave
the shorter the wavelength the more energy the wave has
- Frequency - the number of waves produced in a given amount of time;
- Note that : frequency and wavelength are inversely related, which
means as one decreases the other increases (and vice versa)
- Wave Speed - the speed at which a wave travels
to calculate: wave speed (s) = frequency (f) x wavelength
- Medium (Matter): A material though which a wave travels
-
- Compression: is a region where matter is more closely spaced in a
longitudinal wave.
- Crest: The highest point on a transverse wave
- Trough: lowest point on transverse wave
Exam questions Tricks:

1- The larger the amplitude, the more energy the wave has
2- The shorter the wavelength the more energy the wave has
