an integer number of half-wavelengths.
Radio waves and ultraviolet waves are the same physical phenomenon.The difference is that radio waves have a much greater wavelength.(That's equivalent to saying that they have a much lower frequency.)
nobody is saying that
The airflow from the lungs passed through the lips of the player cause them to vibrate. This creates pressure waves which are tuned and amplified by the length of the tubing in the brass instrument.
Another saying for "dead as a dodo" would be "dead as a doornail."
Somebody's Always Saying Goodbye was created in 1982-11.
Frequency is inversely proportional to the wave length, thus saying the shorter the wave length the higher the frequency and vice versa.The frequency is the number of waves within a time period. As the frequency within that time period increases, the number of waves increases, therefore the width of each wave (wavelength) within that time period has to decrease. Therefore:As the wave length increases, the frequency decreasesAs the wave length decreases, the frequency increases
They differ in wavelength. This is equivalent to saying that they differ in frequency, because the product of (wavelength) x (frequency) is always the same number ... the speed of the wave.

They differ in frequency. (That's exactly the same thing as saying that they differ in wavelength, since frequency and wavelength are firmly connected.) (That's also the same thing as saying that they differ in the quantity of energy carried by each photon, since the amount of energy carried by each photon is firmly connected to frequency.)
Length and volume are not the same, any more than time and mass are the same. They are different properties that are measured with different units.A cube that has a height and length and width of one unit will have a volume of one cubic unit, but that does not mean that it is correct to say that its length and volume are the same. Saying that is like saying that an hour weighs the same as a kilogram.
Because the product of (frequency times wavelength) is always the same number ... it's the speed of the wave. So if one of them changes, the other one has to change in the opposite direction, in order for the product to remain the same number.
"Up a gum tree" is an Australian colloquialism that usually means someone is off on the wrong track, and not on the same wavelength as everyone else.

What it is saying is that to get the Area of a room you must multiply the Length of the room times the Width of the room.It is saying the Length (L) is 15, and the Width (W) is 10.So, now you must multiply the Length (15) by the Width (10) to get your answer (the Area).

It's another way of saying an infinitely long period of time. For ever.
If your phone has a record feature record yourself saying the persons name then assign that voice clip to the person with the corresponding name
