Multiple slit diffraction
Like with the double and single slits well have
interference from multiple slits as well. With
multiple slits you can analyze them in a similar
way to the double slit! If the rays are parallel

constructively or destructively when
light is perpendicular on material with

Why should interference patterns be seen?
For monocromatic light in phase, waves can interfere in two ways
Constructive this is when the waves arriving at the same point have
a path difference equal to an integer multiple of wav

Particles have another angular momentum like quantity called the spin
An analogy to classical mechanics would be the orbit of the earth
around the sun is the orbital angular momentum L and the rotation of
the earth on its axis is the spin S.
Get a mental picture of the sizes
So far what weve talked about for atoms is only their electron
orbitals. However there is much more to atoms than electrons,
they also have a massive nucleus composed of protons and
neutrons. Compared to the total size of

One important area of radiation is how
it interacts with living tissue. Radiation
