The semester exam will be a cumulative exam of all three units: Waves, Electricity and Magnetism & Radioactivity. The main focus will be on electricity and magnetism & radioactivity.

Notice! The first question on the exam will ask you to state the units and symbols for different quantities.

E.g.

Topics include: 

WAVES
- amplitude, frequency, period, wavelength 
- using the wave equation 
- transverse and longitudinal waves 
- wave phenomena (refraction, reflection and diffraction. NO INTERFERENCE, NO STANDING WAVES) 
- using Snell's law 
- the electromagnetic spectrum (you need to know the two extremes. DO NOT MEMORISE THE FREQUENCIES OR WAVELENGTHS) 
- uses of waves 
- sound waves (loudness and pitch)

ELECTRICITY AND MAGNETISM

- basic static electricity (how to create static electricity)
- electric conductors and insulator 
- electric circuits 
- drawing electric circuits 
- how to measure the current and the voltage 
- using Ohm's Law to calculate the voltage, current or resistance 
- Kirchhoff's two laws 
- series and parallel circuits (calculating the total resistance, voltage over components and circuit through different branches) 
- Using the formula P=UI or the variations in order to calculate the power a component in a circuit (e.g. a light bulb) 
- voltage-current graph 

RADIOACTIVITY
- Knowing the three different kinds of radiation and their properties (alfa, beta and gamma) 
- decay equations 
- uses of radiation (thickness control, tracers and sterilising) 
- half life calculations and graphs
