Flashcards do conjunto (29)
- 1What is wave?A wave is a disturbance involving the transfer of energy from place to place.
- 2What are some examples of things that sound waves can travel through?air, water, solid materials
- 3What is the material through which a wave travels?a mediun
- 4Waves that require a medium to travel are called ___________Mechanical waves
- 5____________ is needed to make a waveEnergy
- 6What makes a medium to vibrate?Mechanical waves from a source of energy
- 7How are vibrations repeated?Up-and-down
back-and-forth - 8Moving objects have energy, which they can transfer to a medium to produce ________.waves
- 9What are transverse waves?A wave that vibrates the medium at right angles, or perpendicular to the direction in which the wave travels.
- 10What is the crest?The high point on a transverse wave
- 11The low point of a transverse wave is called _____trough
- 12Transverse waves move up and down on a right line called _____rest position
- 13Make an example of a transverse wave and explain it.When you make a wave on a rope, the rope moves from one end of the rope
- 14What is a longitudinal wave?Is a wave that vibrates the medium in the same direction in which the wave travels.
- 15An area where the coils are together are called_________compresion
- 16What is refraction?An area where the coils are spread out
- 17Make an example of longitudinal wavesIf you push and pull one end of a spring toy.
- 18What is a surface wave?Are combinations of transverse waves
- 19This type of wave travels along a surface that separates two _________.mediums
- 20What movements combine to make each particle of water move in a circleup-and-down
back-and-forth - 21What is speed?The speed of a wave is how far the wave travels in a given amount of time.
- 22How can you determine the wave's speed?dividing the distance it travels by the time it takes to travel that distance.
- 23What is frequency?Is the number of waves that pass a point in a certain amount of time.
- 24In what is measured frequency?hertz (Hz)
- 25frequency is defined as the number of waves per __________second
- 26A wave that occurs every second has a frequency of 1 wave per second. So if 2 waves pass every second the frequency is __________2 Hz
- 27What is wavelength?The distance between two corresponding parts of a wave.
- 28How to find the wavelength of a transverse wave?measuring the distance from crest to crest.
- 29What is the amplitude?Is the maximum distance the medium vibrates from the rest position. The height of the wave's crest depends on its amplitude.
