What is a wavelength?

The distance a wave travels in one second
The height of a wave
The measurement between the distance of two consecutive peaks in a wave
The speed of a wave

The correct answer is: The measurement between the distance of two consecutive peaks in a wave

A wavelength is the distance between two consecutive peaks in a wave. This is different from the distance a wave travels in one second (option A), which is called its frequency. It is also different from the height of a wave (option B), which is called its amplitude. The speed of a wave (option D) is the distance it travels in a certain amount of time, but this does not necessarily have to do with the distance between peaks. So, the best way to define a wavelength is the measurement between two consecutive peaks in a wave. It is a key concept in understanding the behavior and characteristics of waves.
