WAVES 1
What is the definition of a wave?
a disturbance that transfers energy from place to place
What is an example of a transverse wave?
Can you draw one
an ocean wave
What is he definition of FREQUENCY
The number of complete waves that pass a given point in a certain amount of time
Law of REFLECTION
The angle of __________ equals the angle of _________.
The angle of incidence equals the angle of reflection
What is the definition of constructive interference
When waves combine to make a wave with a larger amplitude
What causes an earthquake
rock moving causing the earth to create pressure
What are S Waves
Transverse seismic waves that cause the ground to move back and forth perpendicular to the direction of wave travel. (crests)
What does DMC stand for
DEVIL MAY CRY
what are mechanical waves?
a wave that requires a medium to travel through
a wave that is an oscillation of matter and transfers energy through a material medium
What is the definition of LONGITUDANAL WAVES
Waves that move the medium parraell to the direction in which the waves travel
What is the formula used to calculate frequency?
Speed divided by Wavelength
What is the definition of refraction?
The bending of a wave due to change in speed
What does destructive interference mean
when waves combine to make a wave with a smaller amplitude
What is the definition of seismic waves?
waves that ripple outward in all directions from where the earthquake occurred
Relative speed compared to other seismic waves (S Waves)
slower

boys
What is a medium?
any matter through which a mechanical wave can pass
What is an example of a LONGITUDINAL WAVE
Can you draw one
a slinky
Solve this problem:
The frequency of a wave is 300Hz. If its speed is 1500m/s, calculate its wavelength.
The wavelength is 5
What is an example of refraction
a rainbow
What is the definition of standing waves
A wave that appears to stand in one place
What are P Waves
Longitudinal seismic waves that ___________________________________
travel through the earth by compressing and expanding the ground in the direction of the waves movement
Can S waves pass through liquids
No
What type of angel is Satan considered
a fallen angel
What happens to the medium when it encounters a wave?
It transfers energy to the medium's particles
reflection, refraction, transmission, absorption
What is the definition of AMPLITUDE
The maximum distance that the particles of a medium carrying the wave move away from their positions
What is the definition of reflection?
When an object or wave hits a surface through which it cannot pass it so it bounces back
What is the definition of diffraction
waves hitting a barrier
waves are spread out as a result of passing through a narrow aperture or across an edge, typically accompanied by interference between the waves produced
What is the definition of NODES
The point of zero amplitude in standing waves
What is the relative speed of P Waves compared to other seismic waves
faster
What is the definition of a Tsunami
Earthquakes that occur underwater causing a high sea wave
Satan is a Hebrew word that translates to what English word
adversary
What is the definition of TRANSVERSE WAVES
Waves that move the medium at right angles to the direction in which the waves travel
What is the definition of WAVELENGTH
the distance between two corresponding parts of a wave
Example of a reflection
Mirror
What is the definition of interference
The interaction between waves that meet
What is the definition of ANTINODES
The point in the standing wave where constructive interference occurs. The Amplitude is greater than zero
Can P Waves pass through water
Yes
Where do tsunami waves get bigger
Closer to the shore
What is the definition of Seismograph
A recorded record of ground movements caused by seismic waves as they move
