Examples of mediums… Sound waves = AIR Ocean waves = WATER Not all waves need a medium. Light and radio waves travel through space.
What do they look like? TRANSVERSE WAVES— Have alternating high points (crests) and low points (troughs).
This relationship is always true— as frequency increases, wavelength decreases. f ↑ = λ↓
SPEED = WAVELENGTH X FREQUENCY v = λ x f Example: (do on your own) λ = 3 m, f = 10 Hz
If you’ve ever been knocked over by an ocean wave, you know that the higher the wave, the more energy it carries.
DIFFUSE REFLECTION— ROUGH SURFACES
When the sound waves strike an object, the waves are reflected back the to the bat.
These sound waves form images of her fetus.
The pencil looks like it is broken at the surface of the water.

Waves. What Are Waves? Wave – a disturbance that transfers energy -- the energy transferred through a wave can be carried from the disturbance, through.
Waves Energy is sometimes transferred from place to place by traveling in waves. Sound and light travel in waves. Some substances transport energy through.

What are waves? Def. - Disturbances that carry energy from place to place, through matter or space.
Waves & Sound A. Waves 1. The nature of waves a. A wave is a rhythmic disturbance that transfers energy. b. All waves are made by something that vibrates.
The Behavior of Waves. Reflection Reflection occurs when a wave strikes an object and bounces off of it.Reflection occurs when a wave strikes an object.
All matter is made of _______________ Particles are constantly ______________ As temperature increases, particles move __________ As temperature increases,
A sound is a wave and frequency determines pitch In your mind what is sound? Sound is an example of a mechanical wave and is produced by a vibrating object.
