Question

in a wave, the crest (highest point) and trough (lowest point) are usually represented as uniform or equal from an equilibrium point at 0. indicate the relationship between the crest and trough in the figure below by choosing the greater than, less than, or equal symbol. the absolute value of the crest is ____ the absolute value of the trough.

Explanation:

Step1: Find crest value

The crest (highest point) is at \( +7 \) (from the graph, it reaches up to the \( +7 \) line). The absolute value of the crest is \( |+7| = 7 \).

Step2: Find trough value

The trough (lowest point) is at \( -7 \) (from the graph, it goes down to the \( -7 \) line). The absolute value of the trough is \( |-7| = 7 \).

Step3: Compare absolute values

Since \( 7 = 7 \), the absolute value of the crest is equal to the absolute value of the trough.

Answer:

equal to
