Energy and waves
Cards in this deck (23)
- 1The types of energy areKinetic, heat, light, sound, electric, potential
- 2The types of potential energy areGravitational, chemical, elastic, electrical
- 3Law of ConservationEnergy can't be created or destroyed, only transferred or transformed from one form to another.
- 4MediumMaterial energy travels through
- 5Do waves transfer energy with a transfer of medium?No
- 6What is the shape of a transverse wave?Up and down
- 7What type of energy uses transverse waves?Light
- 8What is the shape of a longitudinal wave?Spring
- 9What type of energy uses longitudinal waves?Sound
- 10What is the name of the highest point a transverse wave is at?Crest/peak
- 11What is the name of the distance between the crests?Wavelength
- 12FrequencyNo. of waves passing a point per second
- 13What is the unit used for frequency?Hertz
- 14What is the name for the volume/loudness of something?Wave amplitude
- 15LightBoth a wave and a particle, and is a form of energy.
- 16Speed=Distance over time
- 17Time=Distance over speed
- 18Light can be slowed down whenIt travels through a medium (material)
- 19RefractionWhen light changes direction as it bounces off the sides of the inside of the material it's travelling through
- 20Angle of incidenceThe angle at which a beam of light enters a material
- 21Angle of refractionThe angle at which a beam of light is at as it leaves the medium
- 22How can you remember the shape of a concave lens?A concave lens has 'caves' in it, meaning the sides curve inwards
- 23What does ROYGBV stand for?The colours of the rainbow: red, orange, yellow, green, blue, violet. (indigo isn't a colour of the rainbow)
