(Frequency) x (Wavelength) = Speed of light.

Note carefully that the "speed of light" in the equation above is the speed of light in the medium that the wavelength is measured in. In vacuum it will be the famous constant "c", but when light travels through any sort of material it's speed is slowed and its wavelength shortened by a factor called the refractive index of the medium. Because wavelength and speed are reduced by the same factor the equation still holds. Light's frequency is not affected by the medium.

Vibrating gasses, like air, produce longitudinal waves of pressure, some of which can be perceived as sound. If the molecules are ionized, they will also produce electromagnetic radiation.

Damped (or free) oscillation occurs when an object is set to vibrate at its natural frequency while forced oscillation involves the application of a force to keep an object in constant or repetitive motion.

electromagnetic waves are produced by the changes in the sub atomic level when heat or electricity is applied to an atom electron which is present in lower energy level will obsorbs energy and jumps in to higher energy level after that it again jumps in to lower energy level.when the electron is jumping in to lower energy level it emitts energy in the form of photons.these transmission of photons is said to be electromagnetic waves.in the electromagnetic waves electric and magnetic fields are perpendicular to each other and also perpendicular to the direction of wave propagation.

EM waves can also be produced by the action of a radio-frequency current in an antenna. Radio transmitters produce power at a single frequency and the antenna acts as a tranducer taking the power from the transmitter and converting it into power that is radiated into space and can be received at a distant point.

yes

yes except light is a transverse wave, and sound is longitudinal wave and needs a median to travel through (which is why light waves can travel through space and sound waves can not)

Take the reciprocal of its frequency, just like any wave of any other shape.

Graphically, the period is the length of time between consecutive occurrences

of the same point in the wave form, just like any other wave.

The only tough part about a square wave is that there are only two points on it

that you can definitely identify in time ... the rising transition and the falling transition.

But that's OK. The time between two rising transitions or two falling transitions is

still the period, even if the square wave is ugly and its positive time and negative

time are unequal, or it has a DC component.

If the transitions are sloped rather than instantaneous, then the zero-crossings are

easily identifiable points in time. These characteristics are all easily spotted on an

oscilloscope.

From the 1O=N_2O_3O- the 3O- can "attack" the N and push the 1O's second bond off the N to form O3N- and from there, any one of the O's is equally likely to put its extra electron pair into a double bond with N, while the negative charge goes back to one of the other two O's which simultaneously attaches to the other and releases the N, forming the original structure. This is possible in part because the extra electron on N in O3N- pushes the O's tightly together.

Wave frequency can be calculated by dividing the speed of the wave (if we're talking about electromagnetic waves in vacuum, that would be the speed of light, c) by wavelength.

For polarization the direction of the oscillation has to be perpendicular to the direction of travel. In sound waves, which are longitudinal waves, this isn't the case and thereby can not be polarized.

Given:

Wavelelngth λ = 4.5 × 10−6 cm = 4.5 × 10−8 m

Speed of light c = 299,792,458 m/s.

Frequency f = c / λ = 299,792,458 m/s / 4.5 × 10−8 m = 6,662,054,622,222,222 Hz

= 6,6620 × 1014 Hz.

For a transverse wave (i.e. the particles conveying the wave move in a direction perpendicular to the direction of wave propagation) the phase velocity (or wave velocity) is the wavelength divided by the period. For a taut string the phase velocity (m/s) is sqrt(F/u) where F is the tension (N) and u is the mass per unit length of the string (kg/m).

It means the disturbance (e.g., pressure difference) goes in the same direction as the direction of the wave. In a transversal wave, on the other hand, the disturbance goes at a right angle.

The basic differences are a signal generator can provide several typical types of waves - square, triangle, sine, etc, and can do so for varying frequencies. In truth, a signal generator is just a very advanced oscillator. A basic discrete oscillator will only be able to provide 1 type of wave, and usually at a very limitted frequency range (control of this can be had in the use of varying inductors and capacitors).

Also, more advanced signal genenerators may have "inputs" as well as "outputs" for more complicated testing.

The biggest disadvantages with oscillators are that they have to be stabilized with control heaters. If the oscillator is operated in a non temperature controlled environment it will drift off frequency and it is not good policy to transmit over a wider that necessary bandwidth. The frequency on either side of the offending transmitter will be affected.
