Physics common task 1
Development of an atom
inside a atom
proton
mass=1 charge +1
neutron
mass=1 charge 0
electron
mass= 1/1860 charge -1
top number on top of atom
protons and neutrons (mass number)
number at bottom of atom
proton number (atomic number)
A atom has a neutral charge because it i has same number of protons and neutrons
plum pudding model
Ball of positive charge with negatively charged particle inside it
What is a wave?
Transverse
the energy transfer is perpendicular to the motion causing it
E.g light Em spectrum, water waves
Longitudinal
The energy transfer is parallel to the motion causing it
E.g sound, ultra sound
A wave transfers energy without transferring matter.
Equation for waves
V=fy
V=wave speed (m/s)
f=frequency (HZ)
y=wave length (m)
