Is glass transparent or opaque to light of frequencies that match its own natural frequencies?
If you speak about seen light, the only way to make transparent glass not light transfering is coloring it with some colors that negate (filter) some other colors
Does the red light from glowing neon gas have only one frequency or a mixture of frequencies?
a mixture of frequencies.
In order for evolution by natural selection to occur what has to happen?
There must be genetic variation, the variation must be heritable, and there must be differential reproduction (due to competition).
Natural selection cannot occur without what?
Variations within a population. Variations mean traits that only certain individuals have that give the individual a greater or lesser chance of reproducing.
When are two populations considered new and separate species?
A new species can occur when;1. Change in allele frequencies-genetic drift can result in loss of alleles in a population-one allele becomes the only variation, becomes "fixed"2. Gene flow due to migration-movement of alleles into or out of a population3. Non-random mating-individuals have preferred mates rather than random4. Mutations-a change in DNA can be beneficial, neutral, or harmful5. Natural Selection-best adapted, more likely to survive
Do chemical reactions only occur in the natural environment?
No. They can occur in the laboratory also.
Do natural disasters occur on other planets?
only if your mom was there.

Why does plutonium not occur in natural ore deposits?
Plutonium occur in deposits of uranium ores but only in ultratraces. In the nature plutonium appear as a result of spontaneous natural fission of uranium isotopes a process with a very low cross section.
What is the range of frequencies?
there are an infinite range of frequencies limited only by the mechanical limitations of the medium creating and transferring it.
Does the red light from glowing neon gas have only one frequency or a mixture of frequencies?
a mixture of frequencies.
What the causes a maximum on a standing wave?
A standing wave pattern is a vibrational pattern created within a medium when the vibrational frequency of the source causes reflected waves from one end of the medium to interfere with incident waves from the source. This interference occurs in such a manner that specific points along the medium appear to be standing still. Because the observed wave pattern is characterized by points which appear to be standing still, the pattern is often called a standing wave pattern. Such patterns are only created within the medium at specific frequencies of vibration. These frequencies are known as harmonic frequencies, or merely harmonics. At any frequency other than a harmonic frequency, the interference of reflected and incident waves leads to a resulting disturbance of the medium which is irregular and non-repeating.
Do physical changes occur in natural processes only?
No. Many physical processes occur by artificial means. Boiling water on a stove or freezing it in a freezer is one common example.
What is electronic filter?
Filter is an electronic device which passes specific frequency and attenuates all other.There are 4 types of filters: 1) Highpass - passes only high frequencies 2)Lowpass - passes only low frequencies 3)bandpass-passes only specefic band of frequencies 4)band reject-passes all frequencies excepting desired band
What natural disasters occur along a subduction zone?
As for I only know, there's only earthquakes and volcanic eruptions...please help!
How many frequencies in a pedoff probe?
only one, we have 5MHz
