What is a Transverse Wave? Describe the oscillations. |
For example with a slinky: The hand movement goes up and down The wave movement goes left to right -The oscillations are perpendicular to the direction of energy transfer. |
|
|
What is a Longitudinal Wave? Describe the oscillations. |
For example with a slinky: The hand movement goes in and out The wave movement goes left to right -The oscillations are parallel to the direction of energy transfer. |
|
|
What is Frequency? What unit is it measured in? |
The number of waves passing a fixed point per second. Measured in Hertz (Hz) |
|
|
What is Amplitude? What unit? |
The maximum displacement that any particle achieves from its undisturbed position. Measured in metres (m) |
|
|
What is Wavelength? What unit? |
The distance from one point on a wave to the equivalent point on the next wave. Measured in metres (m) |
|
|
What is Period? What unit? |
Time taken for one complete oscillation. Measured in seconds (s) |
|
|
What is the Wave Speed Equation? |
Frequency x Wavelength |
|
|
Fill in the gaps: The Electromagnetic Spectrum extends from __________ frequency __________ energy waves to __________ frequency __________ energy waves. |
Low, Low, High, High |
|
|
Why does refraction happen? |
It is due to the difference in the wave speed in the different media. |
