Physics Flashcards
What is a wave
A movement of energy
How is energy transferred
WAVES
Heating
Forces
Electrical current
What is sound caused by
Vibrations
What do vibrations travel through
Medium
What is a medium
Contains particles
How is sound caused
The vibration of an object and particles, which creates sound waves, energy is transferred during this process and can only work by vibrations in a medium
What sort of wave is sound
Longitudinal wave
Which direction does a longitudinal wave energy travel
Energy transfer is parallel to the direction the wave travels
What is a wave made of
Compression
Rarefaction
What is a light wave
Transverse wave
What direction does energy transfer happen in a light
Energy transfer is perpendicular to the direction the wave travels
What is an echo
A hard reflected sound wave
Which surface will create an echo
A smooth, hard and flat surface
Which surface absorbs sound
Rough surface
What happens when a wave is absorbed
It absorbs energy transferred into it and the tempature of the substance increases
Speed of sound
Distance=speed/time
Sound will travel the fasyesy through…
A solid because the particles physically touch and vibrations can be passed from particle to particle easier
