Wave Terminology
What is the term for the highest point of a wave called?
what is a crest?
What do dolphins and whales use to communicate and navigate underwater?
What is bioacoustics or echolocation
What happens when ocean waves slow down and bunch up in shallow water, making their crests steeper?
What is wave shoaling?
What is the term for the fundamental frequency of a musical instrument, which determines its pitch?

What marine mammals are known for using echolocation in sonic seas to navigate and locate prey?
What are dolphins or whales?
What do we call the distance between two consecutive crests or troughs of a wave?
What is a wavelength?
How do oceanographers measure the depth of the ocean floor and find underwater objects using sound waves?
what is sonar?
What’s the term for the point right above the center of an earthquake on Earth’s surface?
what is the epicenter?
When you pluck a guitar string, it produces a sound wave. What type of wave is this, with a shape that resembles a sine wave?
What is a sinusoidal wave?
What device is commonly used to measure the depth of sonic seas and ocean soundings by sending sound pulses and measuring their return time?
What is a sonar?
What term describes the number of waves passing a point in a given time, typically measured in hertz?
What is frequency?
What's it called when sound waves scatter in different directions in the ocean due to temperature, salinity, and pressure variations?
What is Acoustic scattering?
What do we call the waves that cause the ground to shake during volcanic eruptions and earthquakes?
What is seismic waves.
In a wind instrument like a flute or saxophone, what term describes the change in pitch when you change the fingering or valve positions?
What is tuning?
what type of wave is created by underwater earthquakes?
What are seismic sea waves or tsunamis?
What is the lowest point of an ocean wave called?
What is a trough?
In ocean acoustics, what helps scientists measure the distance to underwater objects by timing the delay of sound signals?
What is Echo ranging?
What’s the word for the way waves change direction when they move from one material to another, like when light goes from air into water?
What is a refraction?
The interaction of two sound waves with slightly different frequencies, creating a varying amplitude pattern, is known as what acoustic effect?
What is beat frequency?
What is the speed of sound in water approximately?
What is around 1,480 meters per second?
What is the term that represents the max displacement of a particle from its rest position in a wave?
What is an amplitude?
What's the name for the underwater layer where sound speed changes quickly, causing wave reflection in ocean acoustics?
What is the thermocline?
When ocean waves interfere with each other, creating calm and turbulent areas on the water’s surface, what’s this phenomenon called?
What is a wave interference?
What scientific property of a musical instrument determines its timbre or tone quality, resulting from the unique combination of harmonics and overtones it produces?
What is timbre?
hat term is used to describe the phenomenon where sound waves in the ocean can be trapped and guided by layers of varying water temperature and salinity?
What is sound ducting or sound channel?
