Mathematics of traveling waves: Ocean tides are waves that have a period of 12 hours, an amplitude (in some places) of 1.50 m, and a speed of 750 km/hr. What is the distance between adjacent crests of these waves?
A) 9000 km
B) 32,400 km
C) 9000 m
D) 32,400 m
E) 2500 m

Question

Quizplus · Accepted Answer

The distance between adjacent crests of waves, known as the wavelength, can be calculated using the wave speed and period. The formula is wavelength = speed × period. Given the speed is 750 km/hr and the period is 12 hours, the wavelength = 750 km/hr × 12 hr = 9000 km.
