Quick explanation

Outline a procedure for an experiment demonstrating the refraction of light using transparent blocks of various shapes

  • This point belongs to Refraction of light, especially Refraction of light outcomes.
  • You need to be able to outline a procedure for an experiment demonstrating the refraction of light using transparent blocks of various shapes.
  • The key ideas to know are Describe and Investigate.
  • Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.

Method

Refraction Experiment Method

1. Set up a light source to shine a beam of light towards the transparent block. 2. Measure the angle of incidence as the light hits the block. 3. Observe and measure the angle of refraction as the light exits the block. 4. Repeat for different shapes of blocks.

  1. a

    State the independent variable in this experiment.

    Aim for approximately 1 distinct marking point.
