physics Flashcards
what can you use an oscilloscope to find
the wave length of the sound waves generated
how to use a ripple tank
attach a variable power supply and put a cork bob in the water
what does refraction mean
waves changing direction at a boundary
what does it mean when a wave is absorbed
its energy is transferred to any other material often causing heating
what does it mean when a wave is transmitted
the waves carries on through the material
what does it mean when a wave is transmitted
the waves carries on through the material
what does it mean when a wave is reflected
the waves is sent back
what happens when an object gives out more IR radiation then they absorb
it cools down
how are sound waves created
vibrations
how are the vibrations passed through surroundings
a series of compressions and rarefactions
when do waves have different properties
when they pass through different materials
what occurrences can cause seismic waves
earthquakes and explosions
what happens to the waves that pass through the earth
they will be absorbed or refracted
what are the two types of wave
s-waves and p-waves
how to work out potential difference
work done / charge
