Although you can see the pencil, it appears broken in the glass of water. This is because
Aelectromagnetic waves cannot travel through solids.
Belectromagnetic waves travel at different speeds through different media.
Celectromagnetic waves compress more when they travel through denser media.
Delectromagnetic waves get closer together when they go through dense media like glass.
