Crash Course Light

When electromagnetic waves strike a glass, which most likely happens?

• Some waves are absorbed, some waves are reflected, and some pass through the glass.

• Some of the waves are absorbed, none of the waves are reflected,

  and some pass through the glass.

• None of the waves are absorbed, none of the waves are reflected, and none of them pass through the glass.

• None of the waves are absorbed, some of the waves are reflected,

  and none of them pass through the glass.
