# Why do waves of very low frequency follow the Earth's surface?

Because lower Frequencies are for long range whereas higher frquecies such as microwave go much shorter distances such as line of sight but can carry more information due to …the complexity of the waveform. Do a search for spectrum management and im sure you can find what you are looking for. I just think of a radio wave as the least complex because it is a low frequency and has lots of power behind it to broadcast to a big audience by blanketing a large surface whereas a satellite is a small complex antenna that discharges a high frequecy burst from point to point but can carry alot more information.

# What is frequency?

It is the number of wave crests that pass a fixed place each second. In general terms, it is the number of occurrences per unit of time.

# What is a frequency?

Frequency really means how often a wavelengths repeats itself and is actually related to time. Different wavelengths can be of a single frequency or they can contain multiple,… yet separate frequencies at the same time. One of the ways that wavelengths can be identified, is simply by the frequency. By and large, the frequency used will also tell you a bit about the application in which it's used, as well as the type of frequency you can expect it to be, such as AM, FM, TV, Satellite, or some other type of communications. This is largely in part because there is a published frequency spectrum chart that's available in print and online that identifies most uses for a specific frequency range.

# What is the frequency?

Frequency is defined as the number of cycles per minute. Ex: for a sine wave from " 0 to pi " is a cycle, and this repeats periodically within a interval of time. if frequenc…y of a signal is 50Hz, then you can say that this signal repeats 50 time's a minute..

# What is frequence?

Frequence is how often something has happened. (EG) if you said how frequently do you play football a week an answer to that could be 1,2,3 ... E.C.T

# What is frequencies?

number of occurrences of a repeating event per time.

# Will the earth's frequency ever slow down to zero hertz?

No, Sol will destroy it long before it has the chance.

# What does frequency mean in frequency table?

A frequency table is like a tally chart used to record data. They have their subject and the choices to do from. On the other side they have how many voted or chose that answe…r.

# What has a higher frequency then the fundamental frequency?

The fundamental = 1st harmonic is not an overtone! Fundamental frequency = 1st harmonic. The following tones have a higher frequency: 2nd harmonic = 1st overtone. 3rd harmoni…c = 2nd overtone. 4th harmonic = 3rd overtone. 5th harmonic = 4th overtone. 6th harmonic = 5th overtone. Look at the link: "Calculations of Harmonics from FundamentalÂ Frequency".

# What is your frequency?

Frequncy is the speed of an electrical wave through a conducting material.for example a wave of frequency 50 Hz takes 20 milli seconds(1/50) to complete one cycle.

# A space station is shaped like a ring and rotates to simulate gravity If the radius of the space station is 110 m at what frequency must it rotate so that it simulates Earth's gravity?

[Units omitted] F_centripetal = g = (v^2)/r g = 9.81 (approximately) r = 110 (given) v = 32.85 (aprx.) f = v/(2pi * r) = 0.0475 (ap…rx.) f = 0.0475 Hz

# A space station is shaped like a ring and rotates to simulate gravity If the radius of the space station is 110 m at what frequency must it rotate so that it simulates Earth's gravity In RPS?

Dude, I'm pretty sure it's 0.0475 Hz. A Hz is a cycle per second; in this case a cycle is a rotation, so Hz = RPS.

# How do you get a frequency?

The answer depends on the context: statistical frequencies are different from spectral frequencies.
