wavelength. The larger the frequency, the smaller the wavelength.
fundamental frequency or normal mode. also harmonics are standing waves that combine two standing waves and the fundamental to create a secondary standing wave.
Resonant frequencies
(the Earth's resonant frequencies were first discovered by Nikola Tesla)
I think you mean frequency.
period
speed
frequency
frequencies and wavelengths
for this answer it's false i made a 90 on this test :)
Noise itself, as sound, is a wave. Like any wave except a pure sinusoidal one, a wave can itself be reproduced as the combination of other waves. This process is called the principle of superposition. So certainly then, noise can be produced as the sum of other waves, two, three or an infinite number of them. However, if by "noise" you mean those random-like scratchy amorphous sounds made by TV sets not tuned to any channel, those waves must be made by the addition of many waves of different frequencies, not just a couple of sinusoidal ones.
What we call sound are in fact just pressurewaves propagating through the air. Our ears and brain detect and convert these pressure waves to electric signals which we interprete as being sound. The frequency of these waves determines the altitude of the tone, while the amplitude defines the volume of the sound.When waves (eg pressure waves) pass through openings that have about the same magnitude (or less) than the wavelength of the incident wave, diffraction will occur. Once passed through the opening, diffraction will "generate" a phase difference between waves starting from the top and bottom of the opening. This phase difference leads to interference. Phenomena like diffraction and interference of waves will alter the caracteristics of the incident wave. For example, some frequencies can be cancelled out while others may become bigger. This is what happens in constructive and destructive interference. Different frequencies lead to different sounds because of the connection between frequency and sound.
Yes, if one person holds the rope still whilst the other swings the rope from up and down a transverse wave will be made. If the correct frequency is achieved, a standing wave may be created.

In audio we know the word "bass trap". Bass traps are acoustic absorbers which damp low frequencies to attain flatter low frequency room responses. They are turning sound energy into heat through friction. Possibly you think that standing waves are unable to move. The air appears to vibrate in segments or regions and the fact that these vibrations are made up of traveling waves is not apparent - hence the term "standing wave".

Surface waves (L and R waves) have both higher amplitudes and lower frequencies than body waves, and these low frequencies often match the resonant frequencies of man-made structures
The properties of waves are the same for all sorts of waves. If sound waves reflect it is called an echo. When light waves reflect it is simply called a reflection. Waves on the ocean can also reflect if they run into a cliff instead of a sandy beach. Reflected waves often cause what are called standing waves where waves travelling in opposite directions reinforce each other and cancel each other out. One point of the wave will hardly move and another point will move up and down double the distance it would if there is only one wave. This is very dangerous for boats. Light also can be made to create standing waves. In radio, antennas must be adjusted to get a Standing Wave Ratio of 1:1 so it works for electrical waves in a wire as well. In live concerts, standing waves can mean real trouble for the sound engineers trying to balance the reflected waves from the back of the hall or auditorium. It is often better to have such concerts outside to avoid such problems.
Electromagnetic waves.
It was made by air vibrating called sound waves
Yes, but almost completely as a hobby (ham radio).A2. For communicating with submerged submarines, use is made of Very Low Frequencies,
giant waves made by earthquakes is called tsunamis

No ultrasonic waves are not a form of electromagnetic wave. Ultrasonic waves are nothing more than high frequency sound waves. They can be made with a suitable speaker or transducer.
