Definitions
Define a longitude wave
A longitude is a wave in which particles of the medium move in a direction parallel to the direction that the wave moves.
A wave that moves in a perpendicular direction to the direction that the wave moves.
A transverse wave
A single disturbance that moves from point to point through a medium is called a ___.
A pulse
A wave with a frequency of 14 Hz has a wavelength of 3 meters.
At what speed will this wave travel?
V= 42 m/s
V=14 Hz x 3 M
42 m/s = 14 Hz X 3 M
How are you suppose to enter the room ?
Quietly ready to learn.
Prepared with all materials for class.
Define a transverse wave
A transverse wave is in which particles of the medium move in a direction perpendicular to the direction that the wave moves.
A wave that is not capable of transmitting its energy through a vacuum.
A mechanical wave
If the particles of the medium are vibrating to and fro in the same direction of energy transport, then the wave is a ____ wave.
A longitude
A wave has a frequency of 900 Hz and a wavelength of 200 m.
At what speed is this wave traveling?
V= 900 Hz X 200 M
900 Hz X 200 M =180000 m/s
V= 180000
180000 m/s = 900 Hz X 200 M
Where are you to sit?
In assigned seat
Or any seat that available
Define a electromagnetic wave
A electromagnetic wave that is capable of transmitting its energy through a vacuum.
A wave in which particles of the medium move in a direction parallel to the direction that the wave moves.
A longitude wave
When the particles of a medium are vibrating at right angles to the direction of energy transport, then the wave is a ____ wave.
A transverse
A wave has a frequency of 46 Hz and a wavelength of 1.7 meters.
What is the speed of this wave?
V= 78.2
V= 46 Hz X 1.7 M
78.2 m/s = 46 Hz X 1.7 M
True or False
Are you suppose to listen to teachers Instructions?
True
Define a mechanical wave
A mechanical wave is a wave that is not capable of transmitting its energy through a vacuum.
A wave that is capable of transmitting its energy through a vacuum.
A electromagnetic wave
The main factor which effects the speed of a sound wave is the ____.
Properties of the medium
A wave has a wavelength of 125 meters is moving at a speed of 20 m/s.
What is its frequency?
20 m/s =F X 125 M
20 m/s / 125 M = 0.16 Hz
F= 0.16 Hz
How many jokes do you get a day?
Every one gets 1 joke a day to minimize horseplay.
Define a surface wave
A surface wave is in which particles of the medium undergo a circular motion.
A is in which particles of the medium undergo a circular motion.
Many wave properties are dependent upon other wave properties. Yet, one wave property is independent of all other wave properties. Which one of the following properties of a wave is independent of all the others?
a. wavelength b. frequency c. period d. velocity
D. Velocity
Radio waves travel at a speed of 300,000,000 m/s. WFNX broadcasts radio waves at a frequency of 101,700,000 Hertz.
What is the wavelength of WFNX’s radio waves?
300,000,000 m/s = 101,700,000 Hz X M
300,000,000 m/s / 101,700,000 Hz = M
M= 29.4985 M= 29.5
300,000,000m/s = 101,700,000 Hz X 29.5 M
