Physics 101
1. Define what a wave is?
A wave is the way energy moves from place to place.
2. Name 4 types of waves that are around you?
- sound waves
- radio waves
- water waves
- TV waves
- X-Ray waves
3. Where do waves come from?
Waves come from a disturbance of the particles which is caused by vibrations, when these waves occur they are carrying energy through them.
vibrating particles.
4. In a wave of energy, do the particles move or does the wave move? Explain your response.
The wave moves up and down or back and forth but in each type of wave the particles don't move, This is because the energy is moved by waves through any medium across the room. The wave moves not the particles.
5. Why are waves described as energy-mobiles?
Waves are described as energy-mobiles because the energy is moved by waves through any medium across the room.
6. What are the 2 types of energy waves?
- Transverse waves
- Compression (longitudinal) waves
7. Define what a transverse and a longitudinal wave is.
A transverse waves is a wave where the particle moves perpendicular to the medium.
A longitudinal wave is where the particle moves parallel to the medium.
8. What does perpendicular mean?
Perpendicular means a straight line at an angle of 90° to a given line.
9. Complete the ‘Did you get it?’ section questions.
How does energy move?
Energy moves in the forms of waves.
2. True or false: The particles in a wave move from where the wave starts to where the wave ends up?
False, the Particles remain in the same place its only the wave that moves.
3. What is having work done on it in a wave?
Particles are being moved against a force. Work is being done on them and they are doing work on other particles.
4. What are the two types of waves?
Transverse and longitudinal
5. In which wave do the particles vibrate in the same direction as the wave?
Longitudinal
6. In which wave do the particles vibrate perpendicularly to the direction of the wave?
Transverse
7. What does wavelength mean?
The distance between the crest of two waves.
8. What does amplitude mean?
The height of a wave
9. Which of the following has the longer wavelength?
The one towards the left which is a transverse wave
