Types of Waves/calculations
Calculate the speed of the wave:
frequency (f) = 22 hz
wavelength (λ) = 6 m
132 m/s
How do you calculate frequency?
1 : period (T)
What is an echo?
Echos are the reflection of a sound wave off a surface or boundary, which returns to the listener's ears after some delay.
What is a wave?
A wave is a disturbance that moves through a medium or space, transferring energy without transferring matter.
What are the effects of waves in underwater habitats?
Waves can create new habitats for marine organisms, such as rocky intertidal zones and coral reefs.
Calculate the wavelength of the wave:
wave speed (v) = 50 m/s
frequency (f) = 12 hz
4.17 m
How do you calculate wave speed (v)?
frequency (f) x wavelength (λ)
How do speakers function using waves?
Speakers use waves to produce sound. When an electrical signal is sent to a speaker, it creates a magnetic field that interacts with a diaphragm or cone, which then moves back and forth, producing sound waves.
What is a wave crest and trough?
The crest is the highest point, while the trough is the lowest point of the wave.
What can transverse waves be compared to? (analogy)
Transverse waves can be compared to a wave on a string. Just as a wave on a string moves up and down perpendicular to the direction of the wave's motion, a transverse wave also moves perpendicular to the direction of its propagation.
What are longitudinal, surface, and transverse waves?
transverse wave: vibrates or oscillates perpendicular to the direction it travels.
longitudinal wave: vibrates or oscillates in the same direction that it travels.
surface wave: travels along the boundary or surface between two different materials.
What is wave amplitude?
The distance from the center line (or the still position) to the top of a crest or to the bottom of a trough.
What is a doppler shift?
A Doppler shift, also known as Doppler effect, is the change in frequency or wavelength of a wave in relation to an observer who is moving relative to the source of the wave.
What are the effects of sound waves on nature?
Seed dispersal, Some plants use sound waves to disperse their seeds, such as exploding seed pods or rattling seeds in the wind.
What type of wave is an earthquake
Earthquakes are considered transverse waves.
What is an electromagnetic wave?
An electromagnetic wave is a wave that is created by the oscillation or vibration of electric and magnetic fields and does not require a medium (such as air or water) to travel through.
How do you calculate wavelength?
wave speed (v) : frequency (f)
How are sound created using waves?
Sound is created by the vibration of objects, which creates waves that travel through a medium such as air, water, or solids.
Define harmonic motion
Harmonic motion refers to a type of periodic motion that follows a specific pattern, where the motion of an object repeats itself over time with a regular frequency or period.
What can longitudinal waves be compared to? (analogy)
Longitudinal waves can be compared to a spring. Just as a spring compresses and expands in the direction of its motion when it is compressed and released, a longitudinal wave also moves in the same direction as the vibration that created it.
A mechanical wave is a type of wave that requires a medium (such as air, water, or a solid material) to travel through.
How do you calculate wave period (T)?
1 : frequency (f)
How do sonar devices work?
by bouncing sound waves off objects to determine their location.
What is propagation?
Propagation refers to the transmission or spread of something, such as waves, signals, or diseases, from one place to another through a medium or space.
Where are electromagnetic waves found?
Lightning
