What is a wave?
A wave is a disturbance that travels through a medium from one location to another location caused by a vibrating source.
What is the equilibrium position of a medium?
The equilibrium position of a wave is the level of the medium when no wave is passing through the medium.
What is a wave peak?
The wave peak is the tallest point on a wave that has the maximum amplitude. The peak is also called the crest of a wave.
What is a wave trough?
The wave trough is the lowest point on a wave that has the maximum amplitude.
What is the wavelength of a wave?
The wavelength is the distance between successive peaks of a wave.
What is the frequency of a wave?
The frequency of a wave is the number of wave peaks that pass a fixed point in space in a given unit of time.
What is the period of a wave?
The period is the length of time for one wavelength of a wave to pass a given point in space.
What is the speed of a wave?
The wave speed is the distance one wave travels in a specific unit of time.
What is a medium?
The medium is the matter that a wave travels through.
How are transverse and longitudinal waves different?
In transverse waves, the medium is disturbed vertically in space to transfer the wave energy, while a longitudinal wave disturbs the medium horizontally to transfer the wave energy.
Here are some definitions to help you in your Grade 3-5 Lesson 1 investigation.
Wave – a disturbance that moves through a medium from one place to another place.
Medium – the matter or substance that a wave moves through, such as water or air.
Disturbance – something that causes a wave, such as dropping a rock in water or wind blowing across the top of the water.
Equilibrium Position – the normal level of the water when no wave is passing through the water.
Wave Peak – the highest or tallest point on a wave. The wave peak is also called the wave crest.
Wave Trough – the lowest point on a wave.
Wavelength – the distance from one peak to the adjoining peak.
Frequency – the number of waves (or cycles) that pass a given point in space per unit time.
