The interactions of waves with other waves affect the height of a wave. When wave trains meet other similar ones, if they coincide or phase then amplitude increases (counter interference). But, when the top of one train coincides with the bottom of the other train, the wave trains cancel each other out because of destructive interference.
Frequency is 1 of 3 variables that determine wave energy. The other two are amplitude and velocity.
Some factors that affect the speed of sound waves are density of medium, temperature, direction of wind, and humidity. Remember that a sound wave is just a pressure disturbance that travels through a medium by particle interactions. The nature of the medium will affect the sound waves velocity.
These are also known as planetary waves, and are simply waves in the geopotential height field of the atmosphere. There are typically 3-7 of the at any given time circling the hemisphere.
Squares of prime numbers have three factors.
The prime factors of 30 are: 2, 3, and 5.
Volume, density, and gravity.

The US Army Corps of Engineers (USACE) has developed a Coastal Engineering Manual (CEM) EM 1110-2-1100 in June 2006, in which the significant wave height, Hs, is defined as the mean height of the highest one-third of all waves at a particular location, presumably a buoy station or a stretch of coastline. ( reference CEM Part II, Ch. 1; Section II-1-3.b.3.c)
the accounting method used
The formula is Volume = (1/3)a2h where:a = side lengthh= height
1. wind speed, 2. length of time the wind has blown, 3. fetch
The common factors of 12 and 21 are 1 and 3. One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them. The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 21 are 1, 3, 7, and 21. The common factors are 1 and 3. This means that the greatest common factor is 3. The numbers are 1 and 3
The factors of 15 are 1, 3, 5, and 15. The factors of 39 are 1, 3, 13, and 39. The factors they have in common are 1 and 3. Therefore, the greatest common factor is 3. You can also determine the greatest common factor from their prime factors. The prime factors of 15 are 3 and 5. The prime factors of 39 are 3 and 13. The prime factors they have in common are a single 3, so the greatest common factor is 3.
