Energy of Waves Test
Winneconne Chapter 1 The Energy of Waves Test
Question | Answer |
---|---|
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 |
