Rolling Waves
The Sound of Science
Moving Lights
100
When energy moves from one object to another without changing type.
What is energy transfer?
100
We measure an increase in this when particles start moving faster.
What is temperature?
100
This wave has the vibration moving perpendicular (at right angles) to wave movement.
What is a transverse wave?
100
Sound is energy caused by particles doing this.
What is vibrating?
100
When a ray of light bounces off an object.
What is reflection?
200
When energy changes from one type to another.
What is energy transformation?
200
Heat transfer by contact.
What is conduction?
200
This wave has particles moving back and forth in the direction of wave movement.
What is a longitudinal wave?
200
When the frequency of a sound wave increases, this property of the sound also gets higher.
What is pitch?
200
When a ray of light bends travelling through a medium.
What is refraction?
300
The energy of a moving object.
What is kinetic energy?
300
Heat transfer by movement of particles.
What is convection?
300
The maximum displacement of a particle in a wave; we measure this from the middle of a wave to the peak or trough.
What is amplitude?
300
When the amplitude of a sound wave increases, this property of the sound also gets higher.
What is volume?
300
If light enters a more dense medium, it bends towards this imaginary perpendicular line.
What is the normal?
400
The energy of an object about to fall.
What is gravitational potential energy?
400
Heat transfer by invisible waves.
What is radiation?
400
Closely related to wavelength, this is the number of cycles per second.
What is frequency?
400
The "concert pitch" tone has a frequency of 440 of this unit of measurement.
What are hertz (Hz)?
400
The name given to an incoming light ray, either approaching a reflective surface or a refracting object.
What is the incident ray?
500
The most common (SI) unit for measuring energy.
What are Joules?
500
Insulators like foam and wool work by trapping this inside of them, reducing heat loss by conduction.
What is air?
500
The part of a longitudinal wave where the particles are least dense (i.e. most spread out).
What is rarefaction?
500
When insulating a room for sound, lining the walls with foam reduces the volume by doing this to the sound.
What is absorbing?
500
Light is made up of waves of this type of radiation.
What is electromagnetic?
