Waves Flashcards
(24 cards)
What is an example of a longitudinal wave?
Sound Wave
What is an example of a transverse wave?
Light wave
What is the longest wave on the EM spectrum?
Radiowave
What is a transverse wave?
Oscillations are perpendicular to the direction of energy transfer.
What is Amplitude?
Is the distance from the middle of the wave.
What is a longitudinal wave?
Oscillations are parallel to the direction of energy transfer.
What is a compression?
Tightly packed ,more dense, higher pressure
What is a rarefaction?
Spaces in between a wave
what is the frequency formula?
Frequency=number of waves passed/time
What is the wave speed formula?
Wave speed= frequency X wavelength
What is Propagation?
Direction the wave is travelling.
What is the units of Wave speed?
M/S
What is the period formula?
Period(given)= 1/frequency
What is the magnification equation?
Magnification= image height/object height
What is the frequency of a wave?
The number of waves per second (HZ-Hertz)
What is a period of a wave?
The time taken for each wave to pass a point.
Does a loud sound have a bigger amplitude?
YES!
Does a low pitch sound have a shorter wavelength?
YES!
What is a seismic wave?
It is a shock wave produced by an earthquake.
What does “P” and “S” waves stand for?
P is primary waves which are longitudinal.
S is secondary waves which are transverse.
What are the differences of the P and S wave travelling through earth?
P waves travel FASTER.
S waves CANNOT pass through the OUTER CORE, it is LIQUID.
What effects do P and S waves have at the surface?
P waves cause a one off impact.
S wave causes shaking.
Where is energy stored in a stationary wave?
In a stationary wave energy is stored rather than transferred to other locations.
What is resonance?
The storing of energy in an oscillation or a stationary wave. The energy coming from an external source of appropriate frequency.
