Phisics 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?
-radio waves
-television waves
-cell phone waves
-light waves
3. Where do waves come from?
Waves come from vibrating particles.
4. In a wave of energy, do the particles move or does the wave move? Explain your response.
The waves move. It doesn't take the particles with it but the particles are disturbed.
This is because the waves are traveling around although nothing in the room has to move in order for the wave to get from place to place.
5. Why are waves described as energy-mobiles?
Waves are described as energy-mobiles because the vibration of the particles are disturbing the air around it therefore it connects as more and more air is disturbed. It takes energy around.
6. What are the 2 types of energy waves?
a.transverse waves
b.compression waves
7. Define what a transverse and a longitudinal wave is.
A transverse wave is a wave where the particle moves perpendicular to the medium. up and down.
A longitudinal wave is where the particle moves parallel to the medium. back and fourth.
8. What does perpendicular mean?
Perpendicular means something at an angle of 90°, upright. 90° to the surface.
9. What is a medium?
A medium is the space the particles travel through. For example if you were to shout in water the medium would be water. Same for if you were shouting in a room, the medium would be air.
10. What does parallel mean?
Parallel means side by side and having the same length, the lines will never meet.
11. What is a wavelength?
The wavelength is the distance between the crests of two waves that are side by side.
12. Define what the frequency of a wave is?
The frequency of a wave is the number of complete vibrations or waves made in one second.
13. In sounds waves, what does the wavelength determine?
In sound waves the wavelength determines the wave length of sound.
14. In electromagnetic waves what does the wavelength determine?
In electromagnetic waves the wavelength determines wether the wave is microwave or light ect.
15. Define what amplitude means?
Amplitude means the maximum distance that each particle moves away from it’s usual resting position.
16. What does amplitude determine for sound and light waves?
In sound waves, amplitude determines the loudness
In light waves, amplitude determines the brightness.
17. Write down all of the ‘In a nutshell notes’.
Waves are the way energy moves from place to place.
Waves are energy-mobiles.
Waves move. The particles in the wave only vibrate.
Particles in a wave are moving a distance against a force. They are having work done on them and they can do work.
A transverse wave is a wave where the particle moves perpendicular to the medium.
A longitudinal wave is where the particle moves parallel to the medium.
The wavelength is the distance between two like parts of the wave.
Amplitude is the height of the wave.
A wave is the way energy moves from place to place.
