The distance between identical spots on two waves is called the wavelength.

Here's a breakdown:

* Waves: Waves are disturbances that travel through a medium or space, transferring energy without transferring matter. Examples include sound waves, light waves, and water waves.

* Identical Spots: These are points on the wave that have the same characteristics, such as the highest point (crest) or lowest point (trough).

* Wavelength: It's the distance between two consecutive identical spots on a wave. It's usually measured from crest to crest or trough to trough.
