Question

lesson 26 - waves
label the waves.

image of two wave graphs (blue and red) with dashed boxes and labels \small wavelength\ and \large wavelength\

Explanation:

Step1: Identify wavelength definition

Wavelength = distance between 2 identical points (e.g., peaks).

Step2: Compare wave cycles

Blue wave has more cycles in same distance → shorter wavelength. Red wave has fewer cycles → longer wavelength.

Step3: Match to labels

Blue wave = small wavelength; Red wave = large wavelength.

Answer:

Blue wave: small wavelength
Red wave: large wavelength
