Waves 1
The number of complete waves that pass a given point in a certain amount of time
What is wave frequency?
What causes a wave to start?
When a source of energy causes a medium to vibrate.
A disturbance that transfers energy from place to place.
What is a wave?
What is the equation to find wavelength if you have known values for frequency and wave speed?
Lamda = v/f
Vibrating guitar strings, pendulums and metronomes are examples of this type of wave motion.
What is simple harmonic motion?
This is a wave in which the medium vibrates at right angles to the direction of its propagation
This is a wave vibrating in the direction of propagation
What is a transverse wave?
What is a longitudinal wave?
the distance between successive crests of a wave.
What is wavelength?
What is needed to create a wave?
Waves are created by energy passing through water, causing it to move in a circular motion
Waves with higher energy have BLANK wavelength
What is shorter?
How many total atoms of oxygen are in 2FeSO4?
8
Hammer, anvil and stirrup are this
What is the three bones in the ear that vibrate and allow us to hear?
How does a longitudinal wave move?
It moves the medium the way the wave travels.
amplitude, frequency, period, wavelength, speed, and phase are examples of...
What are the wave properties?
Waves with higher energy have BLANK frequency
What is higher?
When balancing chemical equations you may have to change these numbers
What are coefficients?
What is an example of a wave that doesn't need a medium to travel through?
The light from the sun
Give an example of an longitudinal wave
sound waves
ultrasound waves
Give an example of transverse waves
Ripples on the surface of water
Light
What is the equation for finding wave speed?
v = lamda x f
C3H8 + O2 ---> CO2 + H2O is an example of this type of chemical reaction
What is combustion?
What happens when a wave hits a surface in which it cannot pass?
reflection occurs
What are mediums made of?
Gases, liquids and solids.
how are longitudinal and transverse waves alike, how are they different?
transverse waves oscillate perpendicular to the direction of propagation, while longitudinal waves oscillate parallel to the direction of propagation.
In waves of equal energy, as wavelength increases, what happens to frequency?
The frequency decreases
What are the equations for calculating kinetic energy and gravitational potential energy?
KE = 1/2mv2 and GPE=ham
