What is the amplitude of infrared?
The question is not correctly phrased, Infrared is electromagnetic radiation which consists of waves. Amplitude is a measure of the maximum "strength" or height of the wave and therefore will have a whole range of values from 0 upwards. Infrared does not have a specific range of amplitude however it will have a range of frequencies ( visible light Red end 4 x 1014 Hertz - 3 x 1011 Hertz Microwaves ) and wavelength (visible light Red end 750 nanometres - 1000000 nm nanometres Microwaves)
What are three basic components of all signals?
•Amplitude-Height (loudness) of the wave-Measured in decibels (dB)•Frequency:-Number of waves that pass in a second-Measured in Hertz (cycles/second)-Wavelength, the length of the wave from crest to crest, is related to frequency•Phase:-Refers to the point in each wave cycle at which the wave begins (measured in degrees)-(For example, changing a wave's cycle from crest to trough corresponds to a 180 degree phase shift).
What are three important characteristics of a periodic signal?
Period (or frequency), amplitude and phase. All periodic signals can be broken down into other signals... most commonly sine/cosine waves, but there are others too. These components will each have their own frequency, amplitude and phase that combine into the original signal. The strange part of the question is the phase. A signal on it's own does not have a phase unless you provide some reference signal to compare it to. Generally, this comparison signal is implied by the context of your particular situation. When you decompose a periodic signal into components, however, it is almost always implied that the phase of each component is in reference to the fundamental component (So the fundamental has phase 0, while the others have phases referenced to that). This is done specifically so that each component will combine to create the original signal.
What kind of wave does a microphone make?
A microphone does not generate waves but Rather generates a stream of electrons. Waves needs a medium to propagate like air & water. A broadcasting station does send waves as electrons signals but the medium is not physical
What does a microphone and speaker have in common?
They both convert between electrical impulses and sound waves. The microphone converts sound waves into electrical impulses and the loudspeaker converts electrical impulses into sound waves.
Two waves meet at the same time when one has a instantaneous amplitude of A and the other has the instantaneous amplitude of B Their combined amplitude at this time is?
The amplitudes simply superimpose so it becomes A + B.
What is it called when a combined wave has a smaller amplitude than the origanal waves?
superposition
What is it called when's. Combined wave has a larger amplitude than the original waves?
That is called reinforcement.
Using the concept of interference explain why the sound levels in the room vary?
The sound levels in the room vary because when its loud the waves combine by constructive interference, the combined wave has a larger amplitude than the original waves did but when its soft the two waves with the same amplitude combine by destructive interference, they cancel each other out.
What type of waves have amplitude?
All waves have amplitude.
What do sound waves have in common with other mechanical waves?
They have the same wavelength and harmony. Sometimes the amplitude.
Is it possible for one wave to cancel another wave and the combined amplitude became zero?
yes but no because waves don't crash into each other in the middle of the sea. P.S i am 12
What is a waves amplitude?
The top of a wave, because its cut in half and the waves amplitude is on top...
If a band is playing loudly will the amplitude of the sound waves be small or large?
The amplitude of the sound waves will be largerbecause the larger the amplitude the louderthe sound.
What are micro-waves average amplitude?
microwaves average amplitude
What is it called when the crest of two waves overlap and result in an increased wave amplitude?
Superimposing of waves is when two or more waves travel through the same medium and intersect. The net displacement is the addition of the waves amplitude. If they are in phase they increase amplitude; out of phase, the amplitude decreases.
What occurs when two or more waves overlap and combine?
They superpose. Energy of the waves are redistributed to form a resultant wave with amplitude given by the summation of individual wave's amplitude. If the two waves are of same frequency, speed and amplitude and travelling in opposite direction den stationary waves are form.
