Period: the time it takes for two successive crests to pass a given point. Frequency: the number of waves passing a point in a given amount of time, usually expressed as waves per second. This is the inverse of the period. Speed: how fast the wave travels, or the distance traveled per unit of time.
• The “Problems on Winds, Waves, and Currents” worksheet (Click here for a printable copy of the worksheet). • You may also want to review the “Tides and Water Levels” tutorial (http://oceanservice.noaa.gov/education/kits/tides/), which offers a tutorial on the complex systems that govern
The period (I) is the time taken for each complete cycle of the wave motion. It is closely linked to the frequency (f) by this relationship: quency (in hertz, Hz) = period (in seconds, s) The speed of a wave in a given medium is constant. If you change the wavelength, the frequency must change as well. If you imagine that some
These worksheets will introduce students to wave formation, tides, important currents, and more. The idea is to help students better understand what all that salt water houses. Each short reading passage is accompanied by questions for students.
Periodic Motion and Waves. Speed of sound in air = 340 m/s. Speed of light = 2.9979 × 108 m/s. 1. The crests of an ocean wave are 20 m apart and you measure one wave every 10 seconds (or the frequency = 1/10 Hz). Find the speed of the wave. 2. Tides can be considered to be a big wave.
A wave is described by its wavelength (or the distance between two sequential crests or two sequential troughs), the wave period (or the time it takes a wave to travel the wavelength), and the wave frequency (the number of wave crests that pass by a fixed location in a given amount of time).
Essential Questions. What is sea level and how is it measured? How does sea level affect people, wildlife, and the ecology of the coastline? What forces and physical processes cause sea level to change? How do scientists predict future sea level? Learning Goals. Students will learn the following: .
