- 1What are wavesWave is a disturbance involving the transfer of energy from place to place
- 2What is energyIs the ability to do work
- 3What is mediumIs the material in which a waves travels
- 4What are mechanical waves?Mechanical waves are waves that require a medium to travel
- 5What are the types of mechanical wavesLongitudinal, transverse and surface waves
- 6Mention 3 characteristics of mechanical waves-They need a medium to travel
-They are classified by how they move through a medium
- they have three types - 7How are mechanical waves causedWhen a source of energy causes s medium to vibrate
- 8What is a vibrationQw
- 9What is a longitudinal waveA longitudinal wave is a wave that vibrates in the same direction it travels
- 10Mention three characteristics of longitudinal waves1- an area where the coils are close together are called compression
2- the areas where the coils are spread out are called rarefraction
- are sound waves - 11What is a transverse wave?A transverse wave is a wave that it's medium vibrates perpendicular to the direction wave travels
- 12Mention 3 characteristics of transverse waves1- a high point on a transverse wave is called crest
2- a low point in a transverse wave is called trough
Ex: making a rope move up and down - 13What is a surface waveA surface wave is a combination of transverse and longitudinal waves
- 14Mention 3 characteristics of surface waves- travels along a surface that separates 2 mediums
- ocean waves are the most similar to them bc they both travel through 2 mediums at the Same time - 15What is amplitudeAmplitude is the distance a wave vibrates from the rest position
- 16SpeedIs the quickly a wave moves
- 17WavelengthIs the distance from two corresponding points
- 18FrecuencyIs the amount of times a wave passes through a given point in a certain amount of time
- 19How is a wave's speed related to its wavelength and frequencyThey are related because if the speed is faster more waves will pass and its wavelength would be shorter
- 20How are amplitude and energy relatedIf the energy is more potent the amplitude would be taller but If the energy is low it would be shorter
- 21The 3 ways in which a wave can change directionRefraction, reflection and diffraction
- 22RefractionIs when a wave enters to a new medium so it changes speed so it bends
Ex: when you are on a skate and it changes direction and it goes slower - 23ReflectionIs when light bounces back at you
They are perpendicular
Ex: when you see yourself in a mirror - 24DiffractionIs when a wave moves through a hole in a barrior or around a barrior and then it spreads out
Ex: when light enters through an opening in a barrior - 25What is Constructive interferenceIs when two crests or two troughs combine to create a larger amplitude than the one they had before. They are known by helping each other
- 26What is interferenceIs the interaction between two waves that meet
- 27Destructive interferenceIs the interference that when one crest
