this week in science

this week in science, we discussed the last things that we would need for the test on Monday the 19th.

we discussed that the waves in a pool spread out and bounce off objects just like they do from a light source bouncing off objects.

When there is an object blocking a wave from passing, the part of the wave that is blocked will be stopped and will not pass, but the part of the wave that is not blocked, will pass around the object blocking the other half of the wave.

The other thing we learnt was that the different surfaces that light hits off, has a different texture, so therefore, it reflects the light in a different manner.

We also learnt that when light hits glass, the light would refract because when light goes from a less dense medium to a higher dense medium, the light slows down and changes direction and this is called refraction.

When drawing this refraction, the light always goes through the denser medium and bends down towards the normal line. There is a specific formula but Mr. Finley and Mr. Segen said that doesn't matter.

This is important to us because when water is on our wind shield, the water refracts and makes every thing seem bent because of refraction that takes place when the light passes through the water on the wind shield.
