science 2 Flashcards
what are the two types of energy waves
longitudinal and transverse
what are some features of a transverse wave
has a trough, a peak, and an equilibrium
what is wave frequency measured in
hertz (Hz)
what are some features in a longitudinal wave
compressions and refractions
how do you measure wave speed
speed = distance divided by time
what is a kinetic energy store
anything that moves
what is a thermal energy store
anything with heat
what is the law of energy
it states that enery cant be created or destroyed
what are the four ways evergy can be transferred
thermally, electronically, mechanically and by light snd sound
what is the sankey diagram
the diagram with two arrows, one showing the amount of heat given off and the other one showing the amount of light being given off
what is energy measured in
joules
what does a ray diagram look like
it has the norm, then the reflective surface, and the incident ray then shines onto the reflective surface, and reflects a ray. the angle of incident is always measured from the norm
what are electromagnetic waves
transverse waves
what is the order of electromagnetic waves
radio waves, microwaves, visible light, ultra-violet, x-rays, gamma rays
