?
what are photons?
photons are little packets of energy that have their own particles in order for them to carry themselves through space
1 of 7
what is ionisation?
ionisation occurs when high energy photon hit a molecule which causes it to break up
2 of 7
what is conduction?
in conduction particles transfers energy by colliding with other particles when they vibrate
3 of 7
what is convection?
a convection current is when the heated liquid rises (in a saucepan) and the cold water takes its place
4 of 7
what is radiation?
the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles which cause ionization
5 of 7
what is reflection ?
reflection is when an image or sound(wave) bounces of something and comes and comes back to us
6 of 7
what is refraction
Refraction occurs when a wave moves from a material with one density into a medium with a different density. ... Refraction means that the light waves are bent, or change direction when they enter a new medium.
