In the ListFish directory, "frequency" denotes --in number of days per week or month-- how often a publication is distributed. This number cannot always be precise, especially with discussion lists, but it should give you a good idea of what to expect in your in-box. Very often, discussion lists are listed with a frequency of "7 days" due to the spontaneous nature of the list: in other words, a post could be distributed to the list at any time. Additionally, and again in the case of discussion lists, "7 days" may mean that multiple posts may be distributed on any given day; some particularly active lists, for example, might receive 50 or more posts a day (look for the word "active" in the list's description). If you find that you are receiving more email from a list than you can keep up with, you may prefer to subscribe to the digest version (if available), rather than post-by-post.

When talking about domes, frequency refers to the number of pieces that each edge of the base figure is divided into in the process of triangulating its sides. For instance, we might start with a base figure of an icosahedron and divide each edge of each triangular face into 3 equal lengths. Those new points are connected to divide the original triangle into 9 smaller triangles. Since the original edges were divided into 3 parts, we call this a 3-frequency dome. The frequency is commonly abbreviated as "f", so a 2-frequency dome is called 2f, 3-frequency is 3f, and so forth.

Repeating occurrence.

the number of sound vibrations per second; frequency determines pitch which is the highness or lowness or a sound; the faster an object vibrates, the sound it emits will have a higher pitch, the slower an object vibrates, the sound it emits will have a lower pitch. Therefore, whatever causes an object to vibrate faster or slower, will change the pitch of the sound it makes. For example, a guitar string which is thicker, vibrates slower and will have a lower pitch. A guitar string which is thin will vibrate faster and have a higher pitch. The other way to make a guitar string vibrate slower or faster is by 'shortening' or 'lengthening' it. This is easily done by pressing your finger onto the string which is, in effect, shortening it. A shorter string vibrates faster and will have a higher pitch. Letting go of the string is, in effect, 'lengthening' the string. A 'longer' string will vibrate slower and have a lower pitch.
