We had to make the cardboard perfectly aligned with the others to make the light pass through, because if they weren't the light wouldn't pass and on the whiteboard we wouldn't see the light . With the experiment we can see that light travels in a straight line

To make light go through the hole we have to make the light alined in a parallel way.

 

light travels in a straight path

 

 

 

We had to put nothing in front of the light so that the light can go straight on the wall clearly.

My experiment shows that the light move straight and it can go so far if nothing is in front of it.

The light always travels in a straight line however the condition is.

AnsQ1:To make the light pass through the hole, we need to put the cardboard in a straight line.

 

AnsQ2:Light moves in a straight line.

Light travels in a straight line until something comes between it

If we have to land the light clearly on the white board we have to arange the cardboard and light.
