Unit 3
| Question | Answer |
|---|---|
| What is a disturbance that transfers energy through a medium.? | WAVE |
| Name the material through which a wave travels. | MEDIUM |
| What kind of wave does the particles move BACK AND FORTH in the same direction as the wave, or PARALLEL to the wave. | LONGITUDINAL WAVE |
| What kind of wave does the particles move UP and DOWN in the same direction as the wave, or PERPENDICULAR to the wave. | TRANSVERSE WAVE |
| A type of wave that requires a medium to travel through. | MECHANICAL WAVE |
| What is a measure of how far the particles in the medium move away from their normal rest position. (Displacement) | AMPLITUDE |
| What is the distance from any point on a wave to an identical point on the next wave? | WAVELENGTH |
| Name the highest part of a wave. (Transverse) | CREST |
| Name the lowest part of a wave? (Transverse) | TROUGH |
| What do we call the time required for one cycle of a wave to pass? | WAVE PERIOD OR PERIOD |
| the ___________________________ of a wave tells how many cycles occur in an amount of time. | FREQUENCY |
| What is the unit for frequency? | HERTZ |
| What two things affect the energy of a wave? | AMPLITUDE AND FREQUENCY |
| For mechanical wave, ______________ is most related to energy | AMPLITUDE |
| For Electromagnetic waves, ______________is most related to energy. | FREQUENCY |
| What do you call the speed at which a wave travels? | Wave Speed |
| What medium (type of matter) do waves travel the fastest through? | SOLIDS |
| A disturbance in electric and magnetic fields. | ELECTROMAGNETIC WAVES |
| Why does wave energy decrease over time? | Energy is spread over a greater area. |
| Waves travel the fastest trough solid, liquid or gas? | SOLID |
| What type of waves move at the speed of light in a vacuum? | ELECTROMAGNETIC WAVES |
| A part of longitudinal wave where the particles are far apart. | RAREFACTION |
| A part of longitudinal wave where the particles are close together. | COMPRESSION |
| Electromagnetic waves are ________________ because of the up and down motion of their particles. | TRANSVERSE |
| Sound waves are ______________________ waves because they require a medium. | MECHANICAL |
| When amplitude increase the energy of the wave_________________. INCREASES OR DECREASES | INCREASES |
| If the frequency of a wave increase, what happens to the wavelength? | wavelength shortens. |
| in a vacuum all E M waves travel at the same speed. True or False | TRUE |
