Spectrum through water.

Introduction:
A glass simple prism can be used to split a beam of white light into its component colors. The phenomenon due to which white light splits into component colors is called dispersion.
Question:
Can a beam of light pass through water?
Hypothesis:
My hypothesis of [Can a beam light pass through water?] is that the light will not pass through the water
Materials:
Shallow
bowl
Water
Mirror
Torch
Method:
1.Fill a shallow bowl with water.
2.Place a mirror in this shallow bowl containing water so that it is at an angle of about 30 degrees to the surface of the water.
3.Make the room dark [ Switch off all lights/cover windows with dark cloth or paper ].
4.Shine the torch on the mirror.
Note:
Do this experiment inside a dark room for a better reaction.
Observations: When a beam of light from the torch is shone on the mirror immersed in water, a small spectrum of rainbow colors appears on the ceiling.
Result:
The result was that the rainbow does appear on the ceiling.
Conclusion:
Our conclusion is that the beam of light can pass through the water and reflect off the mirror making a rainbow colour on the ceiling.
Vocabulary:
Spectrum: A band of colors produced when sunlight is passed through a prism, comprising red, orange, yellow, green, blue, indigo, and violet.
Estimated time for experiment:
The estimated time it will take less than 5 - 10 minutes.
