The frequency is also lowered. They're the same thing.
Longitudinal Wave
no, they move horizontally along the direction of the sound wave movement.
Outerspace has no sound. This is because outerspace is essentially devoid of matter, and matter is required for sound. Sound is a physical phenomenon of a travelling pressure wave, and in space there is essentially no gas or media to transmit a wave.
I think the decible is a unit of measure ofpressure in a sound wave.
The determining factor as to the softness or loudness of a sound is the amplitude of the sound wave. We know that sound is mechanical energy, and a source of sound will put mechanical energy into the medium through which it is going to travel. Let's look at the wave. The mechanical wave has a compression phase and a rarefaction phase. In compression, the source compresses the medium to impart energy. In the rarefaction phase, the source will act to decompress the medium. The sound will propagate outward in a series of compression and decompression phases. The difference between a loud and a softer sound is the degree to which a medium is compressed and rarefied during the process by which the sound energy is put into the medium. Fortunately there is a question (and an answer) that goes into this in a bit of detail. It is linked in the Related questions section.
No, the amplitude of a sound wave is determined by the energy or intensity of the sound wave, not its pitch. Pitch is determined by the frequency of the sound wave, which is how fast the wave is vibrating.
A change in frequency is a change in pitch, in terms of sound. try to picture a sine wave in your mind. When you lower the frequency of the wave, it stretches the sine wave out (Which is how the pitch of the sound is lowered. I'm assume that you're question is about Audio.) For example, if you had a sound wave at 440Hz (And is aslo the musical note "A" on the center octave), and you changed its frequency to 329.63Hz, it would then sound lower in pitch (The musical note of "E") I hope that helps ;) ~Mitch
If the frequency of a sound wave is increased, the pitch of the sound also increases, making it sound higher. This means that the number of complete cycles of the wave occurring in a second is increased.
Lowering the frequency of a wave on a string will result in a longer wavelength and a lower pitch sound.
No, the amplitude of a sound wave does not change as the pitch gets higher. The amplitude of a sound wave determines the loudness of the sound, while the pitch is determined by the frequency of the wave.
If the pitch of the sound increases, the frequency of the sound wave also increases. This means that the sound wave is oscillating at a faster rate, creating a higher pitch.
A sound wave's pitch is determined by its frequency; that is its cycles per unit of time. The sound wave's intensity or volume is determined by its amplitude; the maximum crest of a sound wave.
increase the freguency of the wave
the frequency of a sound wave is higher if its wavelength is shorter
The frequency of a sound wave determines the pitch of the sound. Higher frequency waves are perceived as higher pitch sounds, while lower frequency waves are perceived as lower pitch sounds.
The sensation of a frequencies is commonly referred to as the pitch of a sound. A high pitch sound corresponds to a high frequency sound wave and a low pitch sound corresponds to a low frequency sound wave.
No. A sound's pitch depends on the frequency of the wave.
