# Energy of Waves Test

### Winneconne Chapter 1 The Energy of Waves Test

Waves transfer Energy
A Wave can make a leaf bob up and down on the water, but it cannot move the leaf toward the shore. This is because waves transfer only Energy
True or false: Refraction is a property of a wave. True
A section of a longitudinal wave where the particles are spread apart is called a Rarefraction
What is the wavelength a measure of The distance between points on two waves
The equation (V= lambda x f) is called what? Wave Equation
The frequency of a wave is measured using which unit? Hertz
What happens to a wave when it is refracted? The wave is bent
Why do sound waves travel around corners better than light waves? Sound waves bend
When two or more waves share the same space at the same time, it is called Interference
When a wave curves or bends around a barrier what occurs diffraction
How are mechanical and electromagnetic waves different? Mechanical waves require a medium, electromagnetic waves don't.
What forms can a medium take? Solid, liquid, and gas
What happens to a sound wave if there are not particles to vibrate? Example: outter space There would be no sound.
An occurrence in which the crests of one wave overlap the crests of another wave or waves Constructive interference
The bouncing back of a ray of light, sound, or heat when the ray hits a surface that it does not go through reflection
The combination of two or more waves that results in a single wave interference
a occurrence in which the crests of one wave overlap the troughs of another wave distructive interference
a phenomenon that occurs when two objects naturally vibrate at the same frequency resonance
a pattern of vibration that simulates a wave that is standing still standing wave
a change in the direction of a wave when the wave finds an obstacle or an edge, such as an opening diffraction
the bending of a wave as the wave passes between two substances in which the speed of the wave differs refraction
