If Planck's constant could be affected, changed, influenced, impacted, modified,
or revised by anything, then it's doubtful that the scientific community would refer
to it as a 'constant', regardless of how great Planck was.

When a sound wave passes from air into water do you expect the frequency wavelength to change?
The speed of the wave increases, the frequency remains constant and the wavelength increases. The angle of the wave also changes.
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.
If wave speed remains constant what happens to the wavelength of the waves as the frequency?
they all have a direct relationship so one of the variables would have to change to effect the other
Constant is a quantity that does not?
Constant is a quantity that does not change.
What is the name of a value that does not change?
A "constant"
What is a property of sound that changes with frequency?
If you change sound's frequency and hold the velocity constant, the sound's wavelength also changes. If you change sound's frequency and keep the wavelength constant, then velocity also changes.
How does wavelength change when frequency is constant?
the wavelength changes when the frequency changes if the wavelengths are smaller and thinner then the frequency is high, when the frequency is slow then the wavelengths is larger and wider. if the frequency is constant then the wavelength is a normal size
Does the frequency of a wave remain constant if the medium temperature and pressure do not change?
no
How does change in frequency affect kva rating of a transformer?
diz is a controversial question,anyway i write my opinion since E is directly proportional to f (E=4.44fBAT).....therefore the KVA changes on change of frequency.......... this is common thought,but what the controversial thing is why the current can't compensate the KVA rating to maintain it constant........ IN GATE book of G.K publishers the answer is IT DOES NOT AFFECT.
How receiver detect that which is information signal and which is carrier signal and how it separate both at destination?
carrier is constant frequency information is a change from that constant
If the frequency of a water wave changes what must also change?
The wavelength also changes.The product [ (frequency) times (wavelength) ] is the speed of a wave, which is constant.So in order for frequency to change, wavelength must change in the opposite direction, tokeep their product constant.
Which of the following must be true about a photon with more energy A) it must have a lower frequency B) it must have a higher frequency C) it must have a greater Planck's constant D) it must have a s?
B) higher frequency. Planck's constant doesn't change.
Does the velocity of sound change with medium?
Of course,velocity and wave length change.But frequency is constant.
Who you can change th frequency of a constant frequency signal?
Who? Don't you mean what? Your question makes little sense. If the frequency is constant as you say, then it cannot be changed. However, if talking about radio equipment constant frequencies can be changed through a process known as Mixing. That is a second source of constant frequency is mixed in with the other frequency and you will get the sum and the remainder output. In other words, if the frequency of the 1st source is say 5 mhz and the frequency of the other source is 2 mhz, then on the output you would get 7 mhz and 3 mhz. This can be done with other frequencies also. If you are talking about 60hz (USA AC frequency), that can be changed using a VFD or Variable Frequency Drive.
Why frequency remains constant in transformer?
First we know that transformer is a statical electrical device that transfer electrical energy from one circuit to another circuit with out change its frequency .....it may be voltage or current is change simultaneosuly or separately .... and point is why does not change the frequency in the transformer because the there is no moving part in transformer....As we know that frequency is depends upon the rotation....
What effect does a change in media have on the speed of a wave with constant frequency?
You turn into race car.........its freaking awesome i triedit once
When sound enters another medium such as a wall what remains constant?
When sound enters another medium such as a wall, the frequency or pitch of the sound remains constant. The velocity or speed of sound may change depending on the properties of the medium, but the frequency remains the same.
