waves and sound
Distance between wave crests or troughs
wavelength
matter that allows light to pass through
transparent
movement of energy through direct contact
conduction
movement and transfer of energy of charged particles
electricity
devce that is magnetized by current electricity
electromagnet
1 / wavelength
frequency
angle of incidence = angle of reflection
Law of reflection
transfer of energy by movinh liquid or gas
convection
material that does not allow electric charge to transfer easily
insulator
device that converts mechanical energy into electricity
generator
pitch of sound can seem to change if source or listener is in motion
doppler effect
THis lens forms images by refracting light rays together
convex lens
increase in volume caused by increase of energy
thermal expansion
flow of electric charge thorugh a circuit
current electricity
They decrease the voltage of the electric charge
step down transformer
unit to measure volume of sound
decibel
this lens makes images by spreading rays apart
concave lens
Amount of energy needed to raise the tempertaure of 1 gm of water by 1 deg celsius
calorie
This controls the flow of charge in a circuit
switch
Circuit where there are multiple paths along which electricity can flow
parellel circuit
motion of 2 or more waves passing through the same medium at same time
interference
colors produced by mixing primary colors
secondary colors
transfer of energy by electromagnetic waves
radiation
This lowers the amount of electric charge that flows through a device
resistor
path for current electruicity that has little or no resistance
short circuit
