Characteristic of Wave :
Wavelength
Definition : The distance between a a crest to crest or through to through (Distance in a wave cycle) How to find it?
There are 2 ways we can use to find wavelength, first is...
- Speed/Frequency (Wave speed divided by the frequency of the wave).
Second is...
- Looking at the meter written in a diagram
Unit of Measurement :
Measured in "Meters".
Speed
Definition : Speed is the total distance covered by the wave in a given time period.How to find it?
We can find it using a formula..
- Wavelength x Frequency (Wavelength multiplied by Frequency)
Wave cycle
Definition : A wave's crest to crest or through to through.
How to find it?
We can find it by looking at how many crest to crest or through to through there are in the whole wave.
Amplitude
Definition : The distance of a wave from it's resting position and it's crest or through.
How to find it?
We can find it by looking at the meter written in the diagram usually shown in a question.
Unit of measurement : In "Meters"
Period
Definition : Period is the amount of time a wave takes to finish one cycle How to find it?
There are 2 formulas we can use, first is...
- Time/Number of Waves (Time divided by number of waves)
Second is...
- 1/Frequency (1 divided by the frequency of the wave)
Unit of Measurement :
Measured in "Seconds"
Frequency
Definition : The frequency of a wave is the number of waves that pass a point in a certain period of time.How to find it?
There are 3 ways we can find it, first is...
- Number of waves/time (Number of waves divided by the time).
Second is...
- Speed/Wavelength (Speed of the wave divided by it's wavelength).
Third is...
- 1/Period (1 divided by period of the wave).

Classification of Waves
Transverse Wave
- Travel perpendicularly to the direction of the material the wave moves through.
-
Longitudinal Wave
- Travels in a parallel way to the direction of the material that the wave moves through.
Example : Moving a slinky.
