What converts waves into sound?
Sound itself is a wave. Your brain is able to process this wave as sound as it vibrates across your eardrum. The frequency and amplitude of this wave determines how you hear it (what it sounds like), or whether or not you even hear it at all.
How are loudness and and intensity related to the amplitude and energy of a sound wave?
The word loudness belongs to psycho acoustics and tells how we feel this sound, that is not measuring the sound like we do with a sound pressure meter. Listening to music means motion to the ear drums. Only sound pressure moves the ear drums. The energy or the sound intensity is much less important here. Sound intensity belongs more to the noise fighters.
What is the si unit for amplitude?
Amplitude is used for different waves. For a water wave, the amplitude might be measured in units of length (meters or centimeters), for a sound wave, in units of pressure, for an electromagnetic wave, in terms of electrical properties, for an electrical signal, in volts, etc. - so it really depends on the kind of wave.
What is the SI unit of the amplitude of a wave?
We need a length or distance measurement here. The unit is meter or a part of it, like centimeter, millimeter.
Why do some coins ring and others not?
Coins are made of different metals.Metals have their own characteristic modulus of elasticity.Due to this modulus(here Young's modulus)different metals have different frequency of vibration.some rings clearly and some others are low in sound.
What is the relation between amplitude and freq if a transmitter having frequency 500mhz what is the amplitude range if have any formula please tell me about that?
Actually the amplitude depends on your modulator by which you generated your signal you can pick any amplitude you want but here is the formula for frequency modulated signal: Ac here decide the amplitude of the signal and you can see that it is not related to the frequency component of your signal.
What is the difference between FM and AM radio waves?
AM means Amplitude(=height) modulation, so the frequency stays the same and the message is coded into variations of the strength of the signal. FM stands for Frequency modulation. Here the strength of the signal stays the same and the message is coded into changes in frequency instead.
When a waves' amplitude increases does the frequency change?
Velocity of wave = frequency * wavelength (the universal wave equation does not involve amplitude) There is no direct relationship between the amplitude and the wavelength of a wave and therefore if the amplitude increases the wavelength will not necessarily change.
What is the maximum frequency and minimum amplitude that can be measured with the CRO available in laboratory?
Type your answer here... 450000 hz
How exactly does the record work?
Sound is made of waves, these waves are cut into records as grooves. Based on the amplitude and frequency, the groove changes. A needle runs in this groove and transfers the vibrations to a diaphragm. From here a preamp picks up the sound and amplifies it to a level that is reasonable for the stereo to reproduce.
How does the speed of a wave affect its wavelength?
This can be answered using light or sound. Light will remain at a constant speed regardless of frequency or amplitude. Its shift in frequency (Doppler shift) is caused by the extreme distances the light had to travel to get here. Still it remains at the same speed. Sounds speed will change with local conditions. Also subject to an audible Doppler shift when a constant note is moved past you you can hear the pitch shift. The motion compresses the sound as it approaches and spreads it out as it moves away from you.
What is the difference between phase and frequency?
No matter what frequency, there are 360 degrees that can be associated with it (the phase). Here's an equation to summarize: V(t) = A sin ([w*t] + p) A is amplitude w = frequency p = phase shift

Two signals of 2GHz and 4GHz are frequency modulated on same carrier 10?
Definition: In FM technique, the frequency of the carrier signal changes according to the instantaneous amplitude of the modulating signal. Hence, the frequency of the modulating signal is of irrelevance here and the devition from "fc" will be dependent on the amplitude of the same. considering 2GHz and 4GHz to be digital signal the ratio would be 1:1.
What are the 3 ways of producing sound?
By talking, walking, and whispering
What happens when destructive interference occurs waves with different amplitude?
It depends on the frequency of the waves. Are we assuming here that one wave is acting as destructive interference to another wave?. If they have the same frequency, then the amplitudes should combine to produce a wave with a smaller amplitude than the original (two?) waves. Otherwise your results will vary.
