If you wanted the laser to refract less as it exits the prism, you should increase the wavelength of the light.
<h3>What is
refraction?</h3>
Refraction can be defined as a phenomenon which describes a change (bend) in the path taken by light when it's at surfaces between different transparent materials.
According to the model of light wave, the refraction of light is inversely proportional to its wave. Thus, you should increase the wavelength of light, if you want the laser to refract less as it exits the prism.

Blue because usually people will think the color of water is blue so it will match/blend more than red or green
Answer:
2 a) it is less dense than the water
2 b) it is more dense than the water
3 a ping pong ball is hollow and less dense than the water so it quickly bounces up to the surface of the water
