Review: What’s the difference between a transverse and longitudinal wave? What do waves transfer? What are the high and low points of a transverse wave.

Essential Question: How does data collected provide evidence that the amount of energy a wave carries determines the properties of a wave?

WAVES Wave motion allows a transfer of energy without a transfer of matter.

Ms. Barlow’s 8 th Grade Physical Science Class. Waves can differ in how much energy they carry and in how fast they travel. Waves also have other characteristics.

Wave Characteristics and Speed. a traveling disturbance that carries energy through matter or space matter moves horizontally or vertically just a little,

Name three different types of waves.

1. Wave - Rhythmic disturbance that carries energy through matter and space ALL WAVES CARRY ENERGY! Pulse – one wave that travels through a medium Continuous.

Characteristics of Waves. Wave Properties All transverse waves have similar shapes no matter how big they are or what medium they are traveling through.

Amplitude The max. distance the particles move from the “rest position” to: The more energy a wave has → The greater its amplitude Compression or rarefaction.

Calculating Wave Properties

Wave Length Measurement from one point to the next similar point Transverse: crest to crest, trough to trough, node to node, etc Longitudinal: compression to compression, rarefaction to rarefaction SI Unit: meters (m) Represented in equation with the Greek symbol lambda (λ)

Wave Period The amount of time it takes for a wave to complete one cycle (crest to next crest) SI Unit: second (s) Represented by “T” in equations Can be calculated if you know the frequency using the equation: T = 1/f Can also be directly measured

Wave Frequency Number waves that pass a given point in a second SI Unit: Hertz (Hz) 1 Hz = 1 wave/second Represented by “f” in the equation Can be calculated from the period: f = 1/T

vw = λf Wave Speed The rate at which a wave moves SI Unit: meters per second (m/s) Represented by “vw” in equations Can be calculated by multiplying frequency and wavelength vw = λf Can also be calculated as “normal” speed would: vw = d/t
