noun
Etymology: From wave + length.
- The length of a single cycle of a wave, as measured by the distance between one peak or trough of a wave and the next; it is often designated in physics as λ, and corresponds to the velocity of the wave divided by its frequency.

- A person's attitude and way of thinking as compared to another person's.
