How are x-rays produced?
Electrons released from a heated filament accelerate towards a tungsten cathode. Upon collision with the cathode, the KE of the electrons is converted to X-ray Photons.
Electrons released from a heated filament accelerate towards a tungsten anode. Upon collision with the anode, the KE of the electrons is converted to X-ray Photons.
Electrons released from a heated filament accelerate towards a tungsten cathode. Upon collision with the cathode, the change in spin of the electrons causes the release of X-ray Photons.
Electrons released from a heated filament accelerate towards a tungsten anode. Upon collision with the anode, the change in spin of the electrons causes the release of X-ray Photons.

Which of these statements is false?
The photoelectric effect occurs when a photon is absorbed by an electron, causing it to be ejected from its atom. This leaves a gap in the electron shell which is filled by another electron, giving out a photon.
Compton scattering occurs when a photon knocks an electron to a higher orbital level, which causes the photon to lose energy and be scattered.
Pair production occurs when a high energy photon decays into an electron and a positron.

PET scanning involves...
an electron-emitting radio-tracer being injected into the patient. This travels through the body and organs and emits electrons. These collide with positrons causing them to annihilate and release high energy gamma rays.

The Piezoelectric Effect occurs when...
you apply a p.d. across the crystal, which causes it to deform and vibrate at the same frequency. At the right frequency, this will cause the crystal to absorb ultrasound. It also turns an incoming sound wave into a constant voltage, so can be both a transmitter and receiver. 
you apply an alternating p.d. across the crystal, which causes it to deform and vibrate at the same frequency. At the right frequency, this will cause the crystal to absorb ultrasound. It also turns an incoming sound wave into a constant voltage, so can be both a transmitter and receiver.
