wave 1
What is wave frequency?
The number of complete waves that pass a given point in a certain amount of time
What causes a wave to start?
When a source of energy causes a medium to vibrate.
What is a wave?
A disturbance that transfers energy from place to place.
What is a standing wave?
A standing wave is a wave which oscillates in time but whose peak amplitude profile does not move in space.
Give an example of an longitudinal wave
sound waves
ultrasound waves
What is an example of a wave that doesn't need a medium to travel through?
The light from the sun
What are seismic waves?
Seismic waves are waves of energy that travel through Earth's layers, and are a result of earthquakes, volcanic eruptions and so on.
how are longitudinal and transverse waves alike, how are they different?
transverse waves oscillate perpendicular to the direction of propagation, while longitudinal waves oscillate parallel to the direction of propagation.
What is the difference between frequency and angular frequency?
Angular frequency is larger than frequency
What is the difference between a transverse wave and a longitudinal wave?
Transverse waves are always characterized by particle motion being perpendicular to wave motion. A longitudinal wave is a wave in which particles of the medium move in a direction parallel to the direction that the wave moves.
What is a transverse wave? What is a longitudinal wave?
A transverse wave is a wave in which the medium vibrates at right angles to the direction of its propagation
A longitudinal wave is a wave vibrating in the direction of propagation
Where do surface waves travel?
Along the surface of the medium.
What is needed to create a wave?
Waves are created by energy passing through water, causing it to move in a circular motion
What is a traveling wave
A traveling wave is a periodic function of one-dimensional space that moves with constant speed.
Give an example of transverse waves
ripples on the surface of water
a Mexican wave in a sports stadium
What happens when a wave hits a surface in which it cannot pass?
reflection occurs
What are mediums made of?
Gases, liquids and solids.
Could waves of different amplitude interfere?
Destructive interference occurs when waves come together in such a way that they completely cancel each other out.
How dose a longitudinal wave move?
It moves the medium the way the wave travels.
Are all waves built the same?
Different waves, same properties
All kinds of waves have the same fundamental properties of reflection, refraction, diffraction and interference
What is the formula for finding speed?
speed= wavelength x frequency
what are the three types of seismic waves?
What are the wave properties?
amplitude, frequency, period, wavelength, speed, and phase.
What is the difference between a traveling wave and a standing wave?
Travelling waves transport energy from one area of space to another, whereas standing waves do not transport energy.
What is wavelength?
the distance between successive crests of a wave.
