Investigating the Laws of Reflection

Today in Science we did a practical about lights. We also learnt about reflections.

Aim: To investigate how light behaves when it hits a plane (flat) mirror.

Method:
1. Collect a ray box, power supply and single-slit ray slide from your teacher, and set them up to produce a single beam of light.

2. Place a plane mirror on the diagram of the protractor as described below.

3. Vary the angle of incidence and record the angle of reflection in the results table.

Result:

0 degrees = 0 degrees
10 degrees = 10 degrees
20 degrees = 20 degrees
30 degrees = 30 degrees
40 degrees = 40 degrees
50 degrees = 50 degrees
60 degrees = 60 degrees
70 degrees = 70 degrees
80 degrees = 80 degrees

The angle of reflection was the same as the angle of incidence. This could because the mirror we used was just flat and it didn't have any other shapes in it.

What did you find most challenging about the print design process?
I found printing even quality the most challenging when I was printing. It was difficult to print it without any white marks on the print.

What did you find most challenging about the painting composition process?
The most challenging part was drawing thumbnail sketches. Sometimes I had details I wanted to draw but if I were to draw it as a thumbnail sketch then it would be difficult because then I would have to make it small. Some things are better big than small. In this case, I was better off drawing the different designs on the big piece.

What mistake did you make that taught you something?
When I accidentally cut my thumb when I was lino cutting it taught me not to put my fingers in front when I was cutting.

What was most successful about your work?
I think the most successful was when I finished both my print and painting to a good standard.

What could you do to improve your work?
I think if I had chosen better colours for my painting then it would look better. Also, if I had maybe done my printing better it would look better. My printing had a lot of white marks because the oil paint couldn't cover it. If I had rolled out the paint of my cut better then I think it would stop the white marks from coming and my print would be better.

Reflection:

What have I learned about:

I have learnt how to print properly and the different techniques of painting.  I also learned how to cut properly so that I wouldn't cut my fingers again.

I didn't add as many details to my print and painting because I know painting and cutting them would be difficult if I were to add tiny details.
