Question
How many wavelengths pass a fixed point each second. The distance from one point in the wave and the nearest point just like it. A material through which a wave travels. An increase or decrease in frequency as a source and observer move towards and away from one another. How high or low a sound seems to be. A repeating disturbance or movement that transfers energy.
Solution
-
The number of wavelengths that pass a fixed point each second is known as the frequency of the wave. It is measured in Hertz (Hz).
-
The distance from one point in the wave and the nearest point just like it is known as the wavelength. It is usually measured in meters.
-
A material through which a wave travels is known as a medium. This could be a solid, liquid, or gas.
-
An increase or decrease in frequency as a source and observer move towards and away from one another is known as the Doppler Effect.
-
How high or low a sound seems to be is known as the pitch of the sound. It is determined by the frequency of the sound wave.
-
A repeating disturbance or movement that transfers energy is known as a wave. Waves can be classified into mechanical waves, electromagnetic waves, and matter waves.

Fill in the blanks. Choose from the following words, some may be used more than once, others not at all: Doppler, shift, higher, frequency, lower, relative, absolute, reflections, refractions, blood, water, ultrasound, infrasound, movement If a sound source is moving relative to an observer, the sound appears to undergo a change in . If the source is approaching an observer then they will perceive the sound to have a frequency than when it was emitted at the source. The opposite is also true, with a sound from a receding source perceived to be in frequency. This phenomenon of apparent change is called the effect. The change in frequency itself is called the Doppler . The magnitude of the Doppler shift depends on the speed of the source towards or away from the observer. The Doppler effect also applies to of sound off a moving interface. The Doppler effect can be used with to detect and measure the of anatomical structures within the body. For example, the rate of flow through arteries and veins, or through the heart can be measured. The ultrasound beam is reflected off cellular components in the blood, and the observed shift is used to determine the rate of blood flow along the line of sight.
Wavelength is the between one point on a wave and the nearest point just like it.
