To test how light rays work

Aim:

To come up with an experiment to make a rainbow.

Prediction:

I believe that this experimentwill work however only ifthe sun is visible as we needthe sun's rays to refract of thewater in our glasses. I think thisbecause I usually see rainbowsin sunlight.I believe we need this to

experiment to make a

rainbow.

Equipment:

- A glass

- Some water

- Paper

- (proper) Sunlight

Fair Test:

To make this a fair experiment

we kept : the amount of water,

the glass as well as the paper

the same however we changed

: the sun because it changed

positions ; that isn't anything

to make this test unfair however.

Method:

First we poured some water into the cup and came back to our work-station.

Then we had one person hold the cup up to the sun, which is the main reason we split-up into teams, this was a multi-task activity and we needed some extra hands consequently we did just that.

Finally we held the paper down and this is were the unfortunate part comes, we didn't get a rainbow as the sun was hiding behind the shadows of the cloud despite that however we got a small rainbow with the 7 colors after placing it at a specific angle and BANG! We got our self a rainbow henceforth we concluded it as an average experiment.

Results

We saw a rainbow on the bottom of the glass after we held it up at a VERY specific angle furthermore this was probably because the sun was covered in clouds like guards blocking us from it. It was still plausible and there's a time for everything.

Conclusion:

I'm concluding that light travels in a straight line at

299,792,458 meters per second. But when it hits water

or any kind of liquid it refracts if and starts bending in different direction thus creating a rainbow.
