What is a wave?
A wave is a vibration that travels through space and matter, transferring energy from one place to another.
True or False: Waves can only travel through solid mediums.
False
What is the term for the distance between two consecutive crests or troughs in a wave?
wavelength
What are the two main types of waves?
Transverse waves and longitudinal waves.
What is the formula to calculate wave speed?
Wave speed = frequency × wavelength
True or False: Sound waves are an example of transverse waves.
False
What unit is used to measure frequency?
Hertz (Hz)
What do you call a wave that does not require a medium to travel?
Electromagnetic wave
True or False: Waves can interfere with each other.
True
Fill in the blank: The unit of measurement for amplitude is typically ______.
meters (m)
What type of wave is light?
Electromagnetic wave
True or False: All waves carry energy.
True
How do you know energy is being transferred through waves?
We know energy is being transferred because we sae movement
Examples of waves;
Sound waves, light waves, radio waves
What is being transferred during a wave?
Energy
How is sound energy being transferred?
Vibrating particles which collide with their neighbours
How is sound produced?
Sound is produced by vibrating objects
Wavelength definition?
The distance from one peak of a wave to the next peak
Time period definition?
The time taken for one wave to occur
Transverse definition?
A wave that has the direction of energy at 90 degrees to the direction of particale motion
Amplitude definition?
The max distance that the particles in a wave move from their rest position
Frequency definition?
The number of peaks that pass a point per second
Longitudinal definition?
A wave where the direction of energy transfer is the same as the direction of a particle motion
What do waves transfer?
Energy
