Consider two pendulums are oscillating with different frequency . And when these are come in contact with each other after sometime it will oscillate with a frequency intermediate of other two. This new frequency will be resonance when both pendulum is now oscillating with max frequency that can individually acquire.
Wavelength x frequency = velocity, so if the frequency is the same for two waves moving at different velocities, the faster wave must have a longer wavelength.
No, the ear cannot distinguish two pure tones having the same frequency and amplitude.
A sound known as a "beat frequency" will be heard when two sounds of almost (but not quite) the same frequency are mixed together. This is commonly heard when tuning a stringed instrument (such as a guitar) into itself, or when tuning to a standard pitch generator. If the string is vibrating at exactly the same frequency as the standard, then no beat frequency is heard. If the string is vibrating at a just slightly different frequency from the standard, then the interference between the two sounds is heard as a regular "beat". The frequency of the beat is exactly equal to the difference between the two frequencies i.e. if the standard is 440 Hz and the string is vibrating at 441 Hz, then a beat frequency of 1 Hz will be heard.
The most effective frequency at a specified time for ionosperic propagation of radio waves between two specified points: also known as Frequency Optimum Traffic; Optimum Traffic Frequency
A Residential House having two floors or levels.
"Two story" typically refers to a building or house that has two levels or floors. It usually implies that there is a ground floor and an upper floor in the structure.
There are no mosquito on the third floor of a building is because mosquito can only count up to two.
A "story" can be a fictional or non fictional narrative. A "story" can be the space in a building between two adjacent floor levels.
There's a lot more to it than just height, but all other things being equal, a two storey building will be warmer than a bungalow.
Yes
Your answer depends on the square footage to be covered, and not the height of the building.
No- you need an architect.
There's no correct answer to this question. All buildings are different.
Somewhere around 25 ft. side wall.

In downtown Damascus. It is two-story small building with Syria's emblem (Eagle of Saladin) on top.
