A series of ocean waves, each 6.0 m from crest to crest, move past an observer at a rate of 2 waves per second. Calculate the velocity of the waves.

Pepe and Alfredo are resting on an offshore raft after a swim. They estimate that 3 m separates a trough and an adjacent crest of surface waves on the lake. They count 14 crests that pass by the raft in 20 seconds. Calculate how fast the waves are moving.

The speed of surface waves in water decreases as the water becomes shallower. Suppose waves travel across the surface of a lake with a speed of 2.3 m/sm/s and a wavelength of 1.8 mm . When these waves move into a shallower part of the lake, their speed decreases to 1.9 m/sm/s , though their frequency remains the same.  Find the wavelength of the waves in the shallower water?

Suppose you hear a clap of thunder 8.20 s after seeing the associated lightning strike. The speed of light in air is 3.00 ✕ 108 m/s. (a) How far are you from the lightning strike? (The speed of sound waves in air is 343 m/s.)

A marine weather station detects waves which are 9.28 meters long and 1.65 meters high and travel a distance of 50.0 meters in 21.8 seconds. Determine the speed and the frequency of these waves.

Outside temperature over a day can be modeled as a sinusoidal function. Suppose you know the temperature is 60 degrees at midnight and the high and low temperature during the day are 70 and 50 degrees, respectively. Assuming t is the number of hours since midnight, find an equation for the temperature, D, in terms of t. D(t) =

A stationary boat in the ocean is experiencing waves from a storm. The waves move at 56 km/h and have a wavelength of 160 m, both typical values. The boat is at the crest of a wave. How much time elapses until the boat is first at the trough of a wave?

4. Tsunamis are fast-moving waves often generated by underwater earthquakes. In the deep ocean their amplitude is barely noticeable, but upon reaching shore, they can rise up to the astonishing height of a six-story building. One tsunami, generated off the Aleutian islands in Alaska, had a wavelength of 750 km and traveled a distance of 3700 km in 5.3 h. (a) What was the speed (in m/s) of the wave? For reference, the speed of a 747 jetliner is about 250 m/s. Find the wave's (b) frequency and (c) period.

A transverse, periodic wave travels horizontally down a slinky at a speed of 6.91 m/s.  If the period of oscillation is 8.72s, what is the wavelength of this wave (in meters)
