although you can see the pencil, it appears broken in the glass of water. this is because\na electromagnetic waves cannot travel through solids.\nb electromagnetic waves travel at different speeds through different media.\nc electromagnetic waves compress more when they travel through denser media.\nd electromagnetic waves get closer together when they go through dense media like glass.

Brief Explanations:

물에 넣은 연필이 부러진 것처럼 보이는 현상은 굴절 때문입니다. 전자기파는 다른 매질에서 다른 속도로 전파됩니다. 연필이 물에 빠지면 전자기파가 공기와 물 사이에서 굴절되며, 이로 인해 연필이 부러진 것처럼 보입니다.

Answer:

B. electromagnetic waves travel at different speeds through different media.
