    Wave Basics

  1. What is a wave?
  2. What is a vibration?
  3. What are the two main types of waves called?
  4. Give examples of transverse and longitudinal waves.
  5. What is the best way to describe the difference between a longitudinal wave and a transverse wave?
  6. What actually travels as a wave moves along?
  7. What are the correct definitions for Amplitude, wavelength, frequency and speed of a wave?
  8. The Electromagnetic Spectrum

  9. What is the visible spectrum?
  10. What is electromagnetic radiation?
  11. What is the electromagnetic spectrum?
  12. What properties do all electromagnetic radiations have in common?
  13. How fast is the speed of light?
  14. What is a vacuum?
  15. How do we represent electromagnetic radiation in a diagram?
  16. What is a photon?
  17. What is the difference between one kind of electromagnetic radiation and another?
  18. What is beam of electromagnetic radiation composed of?
  19. When a wave travels from one material to another, what never changes?
  20. What is the equation for calculating the speed of a wave?
  21. How do I calculate the wavelength of a wave from a graph?
  22. How do I work out the frequency of a wave?
  23. Reflection and refraction

  24. What are Reflection, Refraction, Diffraction and Total Internal Reflection?
  25. What is Reflection?
  26. What is the "Law of Reflection"?
  27. What is a Normal Line?
  28. How to we work out what happens if there are more than one mirrored surface or reflective boundary?
  29. What is Refraction?
  30. Does anything else happen when waves Refract?
  31. When do waves not change direction when they travel across the boundary from one medium to another?
  32. What is a medium?
  33. What is an interface?
  34. How do we know which medium is most Dense?
  35. Which way does the light bend when it Refracts?
  36. Is there an easy way to remember which direction the light bends when it travels from one material to another?
  37. Does TAGAGA only work for glass and air?
  38. Does anything other than speed and direction change when a wave refracts?
  39. What is Total Internal Reflection?
  40. Why is it called Total Internal Reflection?
  41. Does Total Internal Reflection have any practical uses?
  42. Diffraction

  43. What is diffraction?
  44. How does Diffraction change with different obstacles or gaps?
  45. How can the degree of Diffraction be increased?
  46. What happens if the size of the gap is smaller than the wavelength of the wave?
  47. Are there any conditions on the size of emitters of electromagnetic radiation?
  48. Why must a radio or microwave antennae be around the same size as the wavelength of the radio or microwaves that are being sent or received by the antennae?
  49. Are there any benefits of diffraction?
  50. Does visible light ever diffract?
  51. Does diffraction cause any practical problems?
  52. What does this diagram tell us about the journey of a beam of light?
