The amplitude of a wave is measured from rest to crest or from rest to trough but not from crest to trough. What is the amplitude of the wave in the diagram below? 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.ġ0. If the speed increases, then the wavelength must increase as well in order to maintain the same frequency.ĩ. As a wave travels into a medium in which its speed increases, its wavelength would _.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.Ĩ. The main factor which effects the speed of a sound wave is the _. If the medium is uniform or unchanging, then the speed is constant.ħ. The speed of a wave or a pulse depends upon the properties of the medium. As a pulse travels though a uniform medium, the speed of the pulse _. 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.Ħ. 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 would be vibrating _. In this case, that would be parallel to the line AD.ĥ. In transverse waves, particles of the medium vibrate to and from in a direction perpendicular to the direction of energy transport. The particles of the medium are vibrating _. A transverse wave is traveling through a medium. In transverse waves, particles of the medium vibrate to and from in a direction perpendicular to the direction of energy transport.Ĥ. When the particles of a medium are vibrating at right angles to the direction of energy transport, then the wave is a _ wave.
If energy is transmitted along a medium from the east end to the west end, then particles of the medium would vibrate eastward and westwardĪ sound wave is a longitudinal wave but not the answer since a wave which exhibits this characteristic is not necessarily a sound wave.ģ. If the particles of the medium are vibrating to and fro in the same direction of energy transport, then the wave is a _ wave. A single disturbance that moves from point to point through a medium is called a _.Ī wave is a continuous and repeating disturbance of a medium and a pulse is a single disturbance.Ģ.
