From Wiktionary under the GNU Free Documentation License. Frequency is the number of occurrences of a repeating event per unit time. It is also referred to as temporal frequency. The period is the duration of one cycle in a repeating event, so the period is the reciprocal of the frequency. Loosely speaking, 1 year is the period of the Earth's orbit around the Sun, and the Earth's rotation on its axis has a frequency of 1 rotation per day. The SI unit of frequency is the hertz (Hz), defined as one cycle per second. From Wikipedia under the

Q. If it's not resonant frequency then what is it called? When an opera singer sings at certain frequencies wine glasses shatter. I'm working on a project. Please let me know-thank you. Asked by Jason G. - Fri Apr 16 07:35:29 2010 - - 2 Answers - 0 Comments A. It is called the Resonant Frequency (i.e the object has a naturally occuring resonant frequency).

Pattern baldness in humans is an autosomal, sex-influenced trait; it is dominant in males and recessive in females. A male with at least one copy of the pattern baldness (PB) is bald; however, two copies of this allele must be present for a female to be bald. The frequency of the PB allele in a particular population has been estimated to be 0.3. Assuming random mating, what is the expected frequency of pattern-bald males and pattern bald females in the population? Asked by pinkpanther - Tue Jul 21 18:10:56 2009 - - 1 Answers - 0 Comments A. To make simple, b is allele for baldness and B is for normal. p(B) = 0.7 q(b) = 0.3 According to Hardy-Weinberg: (p + q)^2 = p^2 + 2pq + q^2 So, the frequency of p^2(BB) = (0.7)^2 = 0.49 (normal males and females) 2pq(Bb) = 2 x 0.7 x 0.3 = 0.42 (bald males or normal females) q^2(bb) = (0.3)^2 = 0.09 (bald males and females) Since in males, b is dominant over B; and in females B is dominant over b, then the expected frequency of - pattern-bald males = 1/2 (sex) x (0.42 + 0.09) (baldness) = 0.255 - pattern-bald females = 1/2 (sex) x (0.09) (baldness) = 0.045 and - normal males = 1/2 x 0.49 = 0.245 - normal females = 1/2 x (0.49 + 0.42) = 0.455 Answered by Abu - Wed Jul 22 22:47:25 2009 What generates all of the static on the AM frequency band?
Q. If you use an analog radio frequency adjuster on a radio (the one that is actually a dial or a wheel, and is not digital) and move through all of the AM frequencies that are not used you end up hearing a lot of very different sounding interference and noise. Some of them have a thump-thump-thump and another has a shimmy-shimmy-shwaaa and yet another is just kwisshhshhiwahshsh. So my question is, where do these sounds come from, and why are they different on the different frequencies? If you listen to FM it's all the same universal static at any frequency that is unused. What makes AM different from this? Asked by opticalnoise - Mon Jan 1 18:40:52 2007 - - 4 Answers - 0 Comments A. I'm not sure about all of the noise that comes on the am dial, but I do know that a lot of it is background static created here on earth. First, the am band is a lot lower frequency than the fm band. Every time a lightning strike occurs, your radio will pick that up. The closer it is the louder the interference. Also, I believe that a some of the noise may be white noise receieved from different radio signals that originate in space. Not intelligent life, just as a function of naturally occuring processes.
