Test

We will be having a test on all of the content covered in our unit on light. This will be on Wednesday the 30th of March. This will include;

• What light is
• How light travels through different medium
• Refraction (make sure you know that refraction causes light to shift towards the normal when going from a low to high refractive index, and shifts away from the normal when going from a high to a low refractive index. Also make sure you can explain why refraction occurs). 
• The law of reflection
• Total internal reflection
• Ray diagrams
• Colour
• The eye and parts of the eye

All of this information can be found in the presentations in the "Class Content" tab. 

If you have any questions or concerns feel free to comment on this tab, or email or chat to me in person.
