TRUE or FALSE: The SI unit for frequency is hertz. Where F tens is the tension of the wire and a measure of how tight it is pulled and mu is the linear density of the wire and a measure of how light it is on a per meter basis. The speed of a wave in a wire is given by the equation v = SQRT (F tens/mu) The speed (or velocity) of a wave is dependent upon the properties of the medium through which it moves, not upon the properties of the wave itself.ġ9. Which one of the following properties of a wave is independent of all the others? Yet, one wave property is independent of all other wave properties. Many wave properties are dependent upon other wave properties. This is a basic definition which you should know and be able to apply.ġ8. The _ is defined as the number of cycles of a periodic wave occurring per unit time.
This is true of all waves as they pass from one medium to another medium.ġ7. As a wave passes across a boundary into a new medium, which characteristic of the wave would NOT change?Īs a wave crosses a boundary into a new medium, its speed and wavelength change while its frequency remains the same. If the speed increases, then the wavelength must increase as well in order to maintain the same frequency.ġ6. As a wave travels into a medium in which its speed increases, its wavelength _.Īs a wave crosses a boundary into a new medium, its speed and wavelength change while its frequency remains the same. The speed of a wave is dependent upon the properties of the medium and not the properties of the wave.ġ5. The main factor which effects the speed of a sound wave is the _. If the particles only moved north and not back south, then the particles would be permanently displaced from their rest position this is not wavelike. In longitudinal waves, particles of the medium vibrate to and from in a direction parallel to the direction of energy transport. If the energy in a longitudinal wave travels from south to north, the particles of the medium _. In this case, that would be parallel to the line AD.ġ3. In transverse waves, particles of the medium vibrate to and fro in a direction perpendicular to the direction of energy transport. A transverse wave is traveling through a medium. A transverse wave is a wave in which particles of the medium vibrate to and fro in a direction perpendicular to the direction of energy transport.ġ2. This is the definition of a transverse wave.
When the particles of a medium are vibrating at right angles to the direction of energy transport, the type of wave is described as a _ wave. A longitudinal wave is a wave in which particles of the medium vibrate to and fro in a direction parallel to the direction of energy transport.ġ1. This is the definition of a longitudinal wave. What type of wave is produced when the particles of the medium are vibrating to and fro in the same direction of wave propagation?
