What happens when the vocal cords vibrate at different speeds?
Different vibration frequencies of the vocal cords result in different sounds. This is essential for singers of all kinds. The vocal cords allow for musical sounds of the voice to be expressed.
Two waves that interfere completely result in a wave with a larger amplitude than either of the two initial waves.?
Regardless of the frequency of the wave, all sound:
Which two properties of a sound wave change when a sound gets louder?
It was when the air hit the wave and it move to another direction
Why will sound of low frequencies travel farther in air than sound of high frequencies?
The answer to this question has to do with the nature of waves. A high frequency sound has a greater wavelength than a low frequency sound. A high pitched noise wave looks a bit like NNNNNNNN, whereas a low sound looks a bit more like _____. Because the high pitched noise has a "taller" wave, so to speak, it is more easily interrupted, and cannot, therefore, travel as far as a low sound. sounds with higher frequency have more energy and the energy decreases along with distance and so is the frequency........so a sound with high frequency can travel farther due to its more amplitude,wavelength and intensity. The above is in error. A high frq. sound has a shorter (time is the abcissa(x) axis) wavelength than a lower freq. sound. Tallness or amplitude is not to be confused with wavelength. Amplitude is normally the ordinate or y axis and is a measure of magnitude. Energy content is a factor of both wavelength and amplitude. Lower frequency waves commonly travel better through matter as a result of the atomic spacing of the molecules in the medium( air, solid matter etc.). i.e. Think of dominoes falling.
Why does the white light split into different colors when it passes through the prism?
1) White light is a mixture of different colors in the first place. 2) These colors have different indices of refraction - they bend at slightly different angles when they pass from air to glass.
What is a relationship of frequency and volume and amplitude and pitch?
Frequency is directly related to pitch, where higher frequencies result in higher pitches, and lower frequencies result in lower pitches. Volume is associated with amplitude, where higher amplitudes result in louder sounds and lower amplitudes result in quieter sounds. Essentially, frequency and volume determine the characteristics of pitch and loudness of a sound, respectively.
What is formed when constructive and destructive interference occur at the same time in a wave?
When constructive and destructive interference occur at the same time in a wave, a phenomenon called beats is formed. Beats are periodic variations in amplitude that result from the superposition of two waves of slightly different frequencies.
Is mixing the same as amplitude modulation?
No, mixing is adding two signals together, modulation is more like multiplying two signals. IN mixing, the result has the same frequencies as the input signals. In modulation, the result is the sum and difference frequencies.
What result from wavelengths and frequencies of light and sound?
Different wavelengths and frequencies of light are interpreted as different colours; those of sound are interpreted as pitch.
Each instrument has a unique something that is the result of several pitches blending together through interference thing whats the something?
The unique quality of a musical instrument's sound is called its timbre. Timbre is the result of the various frequencies and overtones produced by an instrument's specific construction and characteristics. These different frequencies blend together to create the instrument's distinctive tone color, or timbre.
What will happen to the amplitude is the harmonics increase?
As harmonics increase, the amplitude will also increase since more frequencies are being added to the original signal. This can result in a more complex waveform with higher amplitudes at multiples of the fundamental frequency. It is important to regulate the amplitude to prevent distortion or clipping in the signal.
Beats are a direct result of what?
Beats are a direct result of the difference in frequency between two sound waves that are interfering with each other. When two sound waves with slightly different frequencies overlap, they create a series of alternating constructive and destructive interference patterns, resulting in the perception of beats.
Two sound waves of the same frequency can interfere with each other but two sound waves must have different frequencies in order to make beats. Why?
When two sound waves of the same frequency interfere, they can either create constructive interference (amplitude adds up) or destructive interference (amplitude cancels out), leading to changes in loudness. However, for beats to occur, there must be a slight difference in frequency to create interference patterns that result in the perception of amplitude modulation. This difference in frequency introduces variation in the interference pattern, causing the beats to be heard.
What is the effect of frequency on amplitude?
The relationship between frequency and amplitude depends on the system being analyzed. In some systems, increasing frequency may result in an increase in amplitude (resonance), while in others it may decrease. Generally, higher frequencies can lead to higher amplitudes in resonant systems, while non-resonant systems may have a more complex relationship between frequency and amplitude.
Can destructive interference occur in waves of different frequencies?
Yes, because propagation speeds may vary. Beware the conventional error in considering only 'frequency' which is a metaphysical conception requiring 'time'. Much confusion arises from this error. The proper 'real' scalar directly producing interference effects is 'WAVELENGTH'.
What is it called when the result of several pitches blending together through interference?
It is called a beat frequency or beat phenomenon. This occurs when two or more pitches with slightly different frequencies interfere with each other, creating a fluctuation in loudness.
What occurs when waves and combine?
If waves are going opposite directions: If the two waves have the same amplitude and frequency, they will cancel each other out, resulting in a flatline. If one has a greater amplitude, it will "absorb" the smaller one and the result will be a wave with amplitude of the difference between the two original waves, going in the direction of the first wave with greater amplitude. If they're going the same direction: If the waves have the same frequency and phase, the will simply add on to each other, resulting in a larger wave. If the two have the same frequency but different phase, some parts of the waves will be offset to result in a wave with different amplitude but same frequency (depending how off-phase the waves are). If they have the same frequency and exactly opposite phases, the two will offset into a flatline. If they have different frequency, then it will result in a completely different wave with different frequency, phase, and amplitude.
