In six seconds,a total of 3 waves crash onto the shore of the beach .
The distance between each wave crest on the water is 8 meters.
Wave length is the length between two wave crests that is the distance between two wave crests.
We know distance between each wave crest is 8 meters
Total of 3 wave crests, the distance between first and second wave crest is 8 meters
the distance between second and third wave crest is 8 meters
So wave length = 8+8 = 16 meters

Answer:
The length of the shadow of the second pole is 16.5 meters
Step-by-step explanation:
Set up a proportional ratio (since the two poles stand side by side).
Cross multiply and solve for x (the shadow of the second pole):
4 · x = 11 · 6
4x = 66
x = 66 ÷ 4
x = 16.5 m
