Explaining Low Frequency and Longitudinal Waves in Fluids

In summary, the conversation discusses the relationship between low frequency and pitch, and why only longitudinal waves occur in fluids. It is explained that pitch and frequency are two words for the same thing, and that low frequency sound waves have a low pitch due to the slower vibrations of our eardrums. The conversation also touches on the Doppler effect and how there are eight cases involving relative motion between a source and observer, but only three formulas are commonly used.

seeking help..please

why do low frequency contributes a low pitch?how?& why only longitudinal in fluids?can any1 please explain to me,tq please..:smile:

The first one, I'm not clear what you are asking: pitch and frequency are just two different words that mean the same thing.

For the second part, you don't get transverse waves because the only way air molecules interact that can produce waves is via pressure. They are not connected to each other, so if one slides past another, there is no force to bring it back to where it started.

A low frequency sound wave has a low "pitch", that is is sounds "low frequency" because our eardrum vibrates more slowly and we interpret that "speed"...Is that what you were asking??

yes,thanks a lot...can i ask a que...the doppler effect actually has 8 cases which involves relative motion between a source and observer..so generally they only have 3 formulas only m i right?
 

1. What are low frequency waves in fluids?

Low frequency waves in fluids are waves that have a lower frequency compared to other waves in the same medium. These waves have a longer wavelength and are typically associated with larger particles or slower movements within the fluid.

2. How do low frequency waves differ from high frequency waves?

Low frequency waves have a longer wavelength and lower frequency compared to high frequency waves. This means that they have a lower energy and travel at a slower speed, making them less noticeable and potentially less damaging.

3. What is the difference between transverse and longitudinal waves in fluids?

Transverse waves in fluids are waves where the particles of the medium move perpendicular to the direction of the wave. Longitudinal waves in fluids are waves where the particles of the medium move parallel to the direction of the wave. In fluids, longitudinal waves are also known as compression waves.

4. How do fluids affect the behavior of low frequency waves?

Fluids can affect the behavior of low frequency waves in a few ways. The density and viscosity of the fluid can affect the speed and direction of the waves. Additionally, the presence of boundaries or obstacles in the fluid can cause reflections or diffraction of the waves.

5. What are some real-life examples of low frequency waves in fluids?

Some examples of low frequency waves in fluids include ocean waves, sound waves in air, and seismic waves in the Earth's crust. These waves have longer wavelengths and lower frequencies compared to other waves in their respective mediums.
