wave movements
what type of wave movement occurs when a wave hits a barrier then BOUNCES right back
reflection

Which non-renewable energy resource is missing: natural gas, coal, _____
oil
What is one con of using wind turbines that involve living organisms?
kills birds and bats
what type of electricity JUMPS instead of flowing in a current with wires
static electricity
what type of wave movement occurs when a wave (like a light wave) bends because it goes through two different mediums---so it goes two different speeds
refraction
what type of wave is a sound wave and has compressions and looks like a slinky?
longitudinal
what part of the em spectrum has the least amount of energy and therefore least likely to hurt us?
radiowaves
hydroelectric power is what we create when we use ___ on rivers
dams
what type of circuit is SIMPLE and if one light goes out they all go out
series
what type of wave movement occurs when a wave hits an obstacle and goes around or goes through a slit and goes through and spreads out from there?
diffraction
what general wave category DOES require a medium to travel?
mechanical
what part of the em spectrum is technically harmful, but if you use long sleeves, a hat and sunscreen you should be fine

resonator
what general wave category does not require a medium to travel
what is the em spectrum source that has the MOST energy and is the most dangerous to us?
