How will a cork behave in water when waves are present ? |
The cork will only Bob up and down It will not move in the direction the wave . |
|
|
What does a transverse wave do? |
Causes particles in a medium(the substance the wave travels though)to vibrate at a right angle to the direction of the waves motion |
|
|
What examsple shows hoe transverse waves work |
|
|
|
A mexican eave is an exsmplr of ehat type of wave ? |
Transverse- the people stand up and sit down in one place but the wave moves perpendicular to the people |
|
|
Describe a spring vibration experiment |
Hold one end in a fixed position Move the other end up and down Observe a wave moving from towards the fixed end of the spring |
|
|
Longitudinal waves do what? |
Cause the mediums particles to vibrate in the same direction as the waves motion. |
|
|
What is the period of a wave |
The time taken to complete one oscillation, (vibration) |
|
|
How is the period of a wave measured? |
Period =1÷frequency Period is measured in seconds |
|
|
What is frequency? |
The number of oscillations per second |
|
|
How is frequency calculated? |
Frequency =number of oscillations÷time Frequency is measured in Hertz (Hz) |
|
|
What is meant by amplitude of a wave? |
Largest distance a wave moves from it's rest position. I. E ( distance from the rest position of a wave to the top of a waves peak) |
|
|
What is meant by wavelength? |
Distance between two adjacent wave fronts . For transverse waves this is the distance between two peaks next to eachother |
|
|
Describe how to do the ripple tank experiment ? |
A rod at one end of a tank creates a series of ripped in water. A bright light is shone through the tank onto paper and the ripple of the water shoe ad a series of parallel lines These ripples are called wave fronts |
|
|
What is the equation for wave speed |
Wave speed (m/s)= frequency(Hz) × wavelength (m) |
