Final Physics Part 2 (5-9)

Conduction

the transfer of heat through direct contact between materials.

Convection

the transfer of heat by buoyant mixing in fluid

Humidity

the density of water vapor in the air

waves

moving disturbance

transverse wave

a wave which oscillations are perpendicular to the wave travel

longitudinal wave

a wave in which oscillations are along to the wave travels

Electric Charge

q = Ne

Resistance

a measure of the opposition to current flow

Ohm’s Law

V=IR or I=V/R

Electromagnetic Wave

a transverse wave that consists of electricity and magnesium

magnetic field

is a force around a magnet that can push or pull on things

superconductor

a material that can carry electricity without any resistance

Solenoid

a cylindrical coil of wire acting as a magnet

Reflection

When a wave bounces back after hitting a surface without passing through it.

Refraction

When a wave changes direction as it passes from one medium to another

Diffraction

when a wave bends around after passing through a small opening.

concave mirror

curved inward

convex mirror

curved outward

plane mirror

normal sized images

nanometer (nm)

10^-9 meter

Polarization

orientation of the oscillations of a wave

Law of Reflection

The angle of incidence equals the angle of reflection

Evaporation

the process by which water changes from a liquid to a vapor

Electric field

An invisible force field caused by an electric charge

current

flow of electric charge
