Transcript of Physics: Waves

Types of Mechanical Waves
Longitudinal Wave:
particles move parallel to direction of wave
Ex: domino effect, sound
Transverse Wave:
particles move perpendicular to direction of wave
Ex: light, coil
Surface Wave:
a combo of both, circular/elliptical paths
Ex: sea waves
How do waves interact with eachother?

Interference:
when two waves meet while moving along the same medium
Constructive:
waves are "in phase"
Destructive:
waves are "out of phase"

Refraction and Diffraction
P and S waves
P waves
(longitudinal)
primary, compressional, acoustic
fastest seismic waves

S wave
(transverse)
secondary waves
can't travel through


Amplitude:
distance from midpoint to crest/trough of a wave
bigger amplitude = more energy
Wavelength:
distance for one cycle
(meters)
V= wavelength/time
Period:
time needed for 1 cycle of a wave
(seconds)
T= 1/frequency
Frequency:
# of cycles in 1 second
(Hertz)
F = 1/time
Wavespeed:
how fast a wave is moving
(m/sec)
V= wavelength x frequency
more stiffness=smaller period=higher frequency

Practice
Problem #1:
If the particles of the medium are vibrating to and from at right angles in the same direction, then the wave is a _____ wave.
a. longitudinal
b. sound
c. standing
d. transverse

Practice
Problem #2:
A transverse wave is traveling through a medium. The particles of the medium are vibrating _____
a. parallel to line AD
b. along the line CI
c. perpendicular to line AD
d. at various angles to line CI
Practice
Problem #3:
What is the wavespeed if wavelength is 20 and frequency is 300 Hz?

Problem #4:
What is the frequency if the period is equal to 20 seconds?
Extra Information
Refraction:
bending of a wave from one medium to another


Diffraction:
waves bounce off a barrier and split


Reflection:
bouncing back from the original wave

Mode:
harmonic mode of vibration

Superposition law:
adding two or more amplitude of waves at a certain time

Practice
Problem #5:
What is the wavespeed if the wavelength is 6 and period (time) is 35 Hz?
