How does light travel?

Thursday 09 May 2019

Today, we predicted how we think light travels. Everybody recorded what they thought: curved lines, zig-zag lines and straight lines.

Then, we used torches and card with holes in to help us found out. When the holes were in an uneven line, the light stopped and couldn’t travel through the holes. When the holes were arranged in a straight line the light could travel through. This showed us that light travels in straight lines.
