What is a wave? Wave – a disturbance or oscillation that travels from one place to another
What is a medium? Medium – the material through which a wave travels When a wave travels through a medium, it transfers energy Air Water Earth
Parts of a Wave Amplitude (A)– the maximum height a wave rises above or below the surface or equilibrium position; a representation of its energy; measured in meters, [m].
Parts of a Wave Wavelength ( λ) – the distance from one point on a wave to the same exact point on the next cycle of the wave; measured in meters, [m].
Parts of a Wave Period (T)– the time, in seconds, it takes for one full cycle (wavelength) of a wave to pass a point
Parts of a Wave Frequency (f) – how many full cycles pass a point in one second, measured in units of Hertz [Hz]
Equilibrium Position – The resting position of the wave; typically the zero position. Parts of a Wave
Graph of a Wave
Parts of a Wave Speed (v)– how fast one wavelength travels in one period of time; measured in meters per second [m/s]
Two Types of Waves Mechanical Waves – require a medium to propagate (Can be transverse or longitudinal) Electromagnetic Waves – do NOT require a medium to propagate (All are transverse)
Water waves Earthquake/seismic waves Sound waves Waves that travel down a rope or spring Types of Mechanical Waves
Radio waves Microwaves Infrared waves Visible light Ultraviolet rays X-rays Gamma Radiation Types of Electromagnetic Waves
Types of Waves Transverse Wave – A mechanical or electromagnetic wave where the oscillations are perpendicular to the direction that the wave moves
Parts of a Transverse Wave Crest – the high point of the wave Trough – the low point of the wave
Types of Waves Longitudinal Wave – A mechanical wave where the oscillations are parallel to the direction that the wave moves
Parts of a Longitudinal Wave Rarefaction – area of a longitudinal wave that is spread out, low pressure Compression – area of a longitudinal wave that is close together, high pressure
Waves Chapter 11 Section 1.
Waves are an important part of the Earth, and not just in the water.
Waves Students will learn about waves. Waves Waves transfer energy without the transfer of mass. A wave is a vibratory disturbance that is transmitted.
Mechanical Waves Types of Wave Describing Waves The Wave Equation.
Chapter 14 Waves/Sound. The Nature of Waves What is a wave? A wave is a repeating disturbance or movement that transfers energy through matter or space.
An Introduction to Waves
Warm Up What is a wave? Name all the parts of a wave you can think of Name all the different kinds of waves you can think of.
What do these pictures have in common?. 2 Introduction to Waves.
Waves Wave Properties. Wave Definitions Wave Rhythmic disturbance that transfers energy Medium Material through which a disturbance travels Mechanical.
- sound in air - AC electricity in a wire -an earthquake in rock -ocean waves in water radio waves - light - infrared radiation - X-rays - gamma rays -microwaves.
Characteristics of Waves SI. What is a wave? A disturbance through a medium as energy is transmitted through that medium Energy is the ability to do work,
WAVES REVIEW & ELECTROMAGNETIC WAVES INTRODUCTION Radio Waves Microwaves Infrared Visible Light (Red, Orange, Yellow, Green, Blue, Indigo & Violet) Ultraviolet.
Waves n Bellringer: What is A wave? (define, use Ch.22 in your book to help you) n What is an example of a wave?
Energy in Waves. A Wave is… Any disturbance that transmits energy through matter or space. Energy in Waves.
Pg /10/13 Waves and the Electromagnetic Spectrum A wave is a disturbance that transfers energy from place to place. Most waves need something.
What is a Wave? Sound and Light are forms of energy that travel in waves A wave is a repeating disturbance or movement that transfers energy through matter.
