Test 1 Study Guide
Question | Answer |
---|---|
What is a wave? | It is a disturbance that transfers energy from place to place. |
What is energy? | It is the ability to do work. |
What is a medium? | The material through which a wave travels. |
What are the different types of waves? | The three types of waves are longitudinal waves, transverse waves, and surface waves. |
Wat are the three different types of mediums? | The three mediums are solids, liquids, and gases. |
what are the different parts of the wave? | The crest, trough, wavelength, amplitude. |
What is a crest? | The highest part of the wave. |
What is a trough? | The lowest part of the wave. |
What is amplitude? | The maximum distance the particles of the medium carrying the wave move away from their rest position. |
What is compression? | The part where the coils of a wave are close together. |
What is rarefaction? | The parts of the wave where the coils are spread out. |
What is reflection? | When a wave hits a surface that it cannot pass through, it bounces back. |
What is refraction? | Bending of waves due to change of speed. |
What is diffraction? | The bending of waves at the edge of a barrier. |
What is constructive interference? | When two waves combine to make a wave with a larger amplitude. |
What is destructive interference? | When the amplitude of two waves combine with eacher other producing smaller amplitude. |
What are the four basic properties of a wave? | Amplitude, wavelength, frequency, and speed. |
What is the formula for calculating the speed of the wave? | Frequency X Wavelength = Speed |
What is the unit for the frequency of a wave? | hertz (Hz) |
What is the angle of incidence? | The angle between the incoming wave and the imaginary perpendicular line. |
What is the angle of reflection? | The angle between the reflected wave and the imaginary perpendicular line. |
What is diffraction? | The bending of waves |
What is the wavelength? | The distance between two corresponding parts of a wave. |
What is amplitude? | The maximum distance the particles of the medium carrying the wave move away from the resting position. |
What are longitudinal waves? | Waves that move the particles of the medium parallel to the direction that the waves are traveling. |
What are transverse waves? | Waves that move the medium at right angles to the direction in which the waves are traveling |
What are surface waves? | Waves that are a combination of transverse adn longitudinal waves. |
What is the amplitude? | The maximum distance the particles of the medium carrying the wave move away from their rest positions. |
What is frequency? | the number of complete waves that pass a given point in a certain amount of time. |
What is speed? | how far the wave travels in one unit of time, or distance divided by time. |
