Refraction of Light

Isaac Newton

performed his experiment using a triangular block of glass called a prism.

Parallel rays of light

can be focused in to a focal point.

Refraction

: the bending of light (it also happens with sound waves, water waves and other waves) as it passes from one transparent substance into another.

Biconcave lens

: curves are thinner at the middle than it is at the edges.

light travels

When from air into water, it slows down, causing it to change direction slightly.

Refraction

can create a spectrum.

These seven colors are remembered by the acronym ROY G BIV

red, orange, yellow, green, blue, indigo and violet
