Now, light is a transverse wave, meaning that the wave travels in one direction and oscillates back and forth in a direction that's perpendicular to the direction of travel.

现在，光是一种横波，这意味着波沿一个方向传播，并在垂直于传播方向的方向上来回振荡。

These electromagnetic waves are a type of transverse wave, which means both fields, electric and magnetic, act in directions that are perpendicular to the direction in which the wave is moving.

这些电磁波是一种横波，这意味着电场和磁场都在垂直于波移动方向的方向上运行。
