This is a breakdown of all of the content that will be on your AP2 exam paper 2 and covers all of the topics in the physics unit. Use this, your books, the flash cards and all of the resources on google classroom to identify your strengths and areas that you need to work on in preparation for your exam.

 Question content     Explain the differences between longitudinal and transverse waves. Label on a diagram of a wave the direction of energy transfer. Label on a diagram of a wave the amplitude, peak, trough and wavelength. Identify the different parts of the electromagnetic (EM) spectrum.  Calculate the speed of a wave using the equation V = f x λ  Label the normal, incident ray and reflected ray on a ray diagram.  State what would happen to the angle of reflection if the angle of incidence was changed. Identify words that would describe a reflection. State what refraction is. State when refraction will and will not happen. Complete a diagram to show the refraction of a wave. Interpret data to write a conclusion. State 2 properties that are the same for all EM waves.  State why microwaves are used in communication involving satellites.  Explain why radio waves and microwaves have different properties when it comes to their uses in communication. Calculate the frequency of a wave using the equation V = f x λ and using standard form.  State the range of wavelength of the EM spectrum. Give examples of how some of these waves are used in communication.  Interpret data to come to a conclusion about the risks of EM waves on our health. Describe the structure of an alpha particle. Identify which ionising radiation is the most, moderately and least ionising. State what happens to the structure of an atom when it is ionised. State precautions people working with radioactive materials should take to reduce irradiation.  State examples of natural and man-made sources of background radiation.  Suggest why the reading on a Geiger counter may be different.  Complete the nuclear equation to show what happens to an atom during alpha and beta decay.  Calculate the half-life of a material using a graph.  Identify which ionising radiation is used in an experiment and explain why.  State the properties of of a radioactive source to be used in medical diagnosis.  Describe the properties (penetrating ability, range in air and deflection in a magnetic field) for alpha, beta and gamma radiation.
