Investigation between the angle of Incidence and detraction

To help to complete this I shall draw up an equipment list before hand to help to make my investigation run smoothly the list is as follows: 1. A ray box

2. A Pyrex block

3. A sharp pencil

4. Sheets of paper

5. A protractor and a ruler

This is all of the equipment which I will be needing for my investigation.

In addition to this I shall also draw up a step by step also to help my investigation to run smoothly this is my step by step:

. collect and set up all equipment

2. Measure the angle out which I need the ray of light to travel through the block

3. Place the blok onto the page of paper and line up the ray box so that the ray is shining through the block at the angle which I require

4. Turn on ray box so that ray is shining through the block and record the line in which the ray is coming out of the block by making marks on the page where is line is traveling

5. Join the marks up on the page and make sure that they are all running in a straight line

6. Measure using a ruler the distance which the two different lines are apart from one another

This concludes my step by step

As this investigation is not using any hazardous materials there is, no special safety features which I will need to follow other than the normal lab safety features

Now I shall go and complete the experiment to get my results
