Pratical

• what does the practical of reflection and refraction do

  measure the angle of reflection and refraction
• What equipment is needed

  Slit,ray box,lens to create a narrow light
• Steps of the practical (reflection pratical)

  • create a straight line on the paper and use a protractor to make a 90 degree angle
  • Place glass blox so normal is in the centre
  • Turn off the light
  • Use ray lock so light hit the box at the normal(angle of incidence
  • Mark the angle of incidence the transmitted and the reflected ray
  • Turn on the light and remove blox
  • Measure angle of in idence reflection and refraction
• after repeating experiment with a different material what should be the result

  the angle of reflection should stay the same but the angle of refraction should change
