The figure below shows a PN junction diode used in a rectifier.

The figure below shows a PN junction diode used in a rectifier.

i. What type of rectification is shown?
ii. Describe how the rectification is achieved.
iii. State two disadvantages of this rectification.
iv. In the space provided below, sketch the output signal displayed on the CRO during the rectification process.

---

(i) Half-wave rectification
(ii) During the first half cycle, the diode is forward biased, hence current flows in the second half cycle, the diode is reverse biased therefore no current flow. In the next cycle, the process repels itself.
(iii) - Output cycle is not smooth.
- Power loss at the half-cycle is eliminated.

  The figure below shows the cross-section of a ripple tank full of water. a piece of cork floats
  on the surface of water and a straight edge vibrator placed at shallow end A to generate waves that travel to deep end B.
  
  i. Name the type of wave generated on the water surface.
  ii. The cork is observed to stay put despite passing water waves. Explain this observation.
  iii. It was estimated that successive waves pass the cork every 0.25 seconds. If the speed of the waves is 0.28m/s, determine
  the frequency and wave length of the waves at that point.
  iv. Sketch the wavelength as viewed from a point above the ripple tank.
