Transverse Waves
When you measure crest to crest of transverse wave
Wavelength
rarefaction to rarefaction
Compression to compression
Wavelength
How are electromagnetic waves made?
vibrating electric and magnetic fields
What is the wave speed equation for all types of waves?
Wave speed = wave length x frequency
This occurs when a wave strikes an object and then bounces off of it.
Reflection
Amplitude
How does the amplitude change if the compressions of a wave get tighter and rarefactions get further apart?
It increases
What medium does electromagnetic waves travel fastest through? (Solids, liquids or gases)
Gases
What is the speed of a wave with a wavelength of .05m and a frequency of 50 Hz
2.5 m/s
the bending of a wave caused by a change in its speed as it travels from one medium to another.
Refraction
The number of waves that pass by a point each second
Frequency
What type of medium do sound waves travel through quickest? (Solid, liquid or gas)
Solids
What type of electromagnetic waves are we able to see?
Visible Light
What is the frequency of a wave that is travelling with a speed of 3,000 m/s and has a wavelength of 0.01m?
Include UNITS of frequency.
300000 Hz
The bending of a wave around an object.
Diffraction
The time it takes one wavelength to pass by a point
Period
The number of waves that pass by each second
Frequency
As frequency of a wave increases, what happens to the wavelength and energy or a wave?
Wavelength - decreases
Energy - increases
What is the wave length a wave that is travelling at a speed of 4775 m/s and has a frequency of 700 Hz?
6.82 m
The process of two or more waves overlapping and combining to form a new wave. The new wave can only exist while the two original waves continue to overlap.
Interference
wave speed = wave length x frequency
The amount of time it takes on wave to pass by a point
Period
What type of wave has the highest energy, highest frequency and lowest wavelength on the magnetic spectrum?
Gamma Waves
If frequency of a wave increases how does this effect the waves speed?
Increase the waves speed
The process by which an object is made to vibrate by absorbing energy at its natural frequencies.
Resonance
