No if you say drop a heavy rock out of water it would make a loud low bang but in water it makes a higher pitched noise.

Which physical quantity remain unchanged when light and sound passes through medium?
Its FREQUENCY remains the same. Remember that when sound waves travel from air to water, its frequency remains the same, which is why people do not seem to have higher or lower voices under water. However the amplitude and velocity do change if it is a sound wave.
What happens to the wave when you increase the wavelength?
More energy would be transferred in the wave, so a sound wave would get louder and a light wave would get brighter. The wavespeed, frequency, and wavelength of the wave will remain the same.
A cork floats on the water as a wave passes by What happens to the cork Will the cork's vibrational frequency be related to the water wave's frequency and if so how?
The cork will move up and down with the wave, since the wave is a transverse wave. I would think that the frequency should be the same as the wave.
Why when frequency of a wave increases the wavelength decreases?
Because the product of (frequency times wavelength) is always the same number ... it's the speed of the wave. So if one of them changes, the other one has to change in the opposite direction, in order for the product to remain the same number.
How does a decrease in velocity affect the frequency and wavelength of the waves entering the shallow water?
The frequency stays the same and wavelength decreases
What happens to the wave length when the frequency of a wave is doubled but the wave speed stays the same?
The wave length would necessarily be one half. The speed would remain the same independent of the frequency.
How do you differentiate FM from PM signal?
A: FM means frequency Modulation meaning the frequency remain the same. pulse modulation the frequency can vary

How is the intelligence signal modulated in the carrier?
If the intelligence signal striking a microphone was doubled in frequency from 1 kHz to 2 kHz with constant amplitude, (fc) would change from 1 kHz to 2 kHz. Because the intelligence amplitude was not changed, however, the amount of frequency deviation above and below fc will remain the same. On the other hand, if the 1 kHz intelligence frequency were kept the same but its amplitude were doubled, the rate of deviation above and below fc would remain at 1 kHz, but the amount of frequency deviation would double.
Is the frequency of an electromagnetic wave will remain the same if its wavelength is increased?
No. The product of (wavelength) times (frequency) of an electromagnetic wave is always the same number ... the speed of the wave. So if one of those quantities increases, then the other one must decrease by the same factor, in order for the product to remain constant.
What happens to the wave when you increase the wavelength?
More energy would be transferred in the wave, so a sound wave would get louder and a light wave would get brighter. The wavespeed, frequency, and wavelength of the wave will remain the same.
How the wavelength of waves traveling with the same speed would change if the frequency of the wave increases?
The product of (wavelength) times (frequency) is always the same number ... the speed of the wave. So if either of them changes, the other one changes by exactly the same factor in the other direction, in order for the product to remain coinstant.
Is the number of mole remain same if you add distilled water?
Yes, the number of moles will remain the same as long as the chemical does not react with water.
Will a step up 110 to 22o volts converter change the cycles too?
No. Frequency will remain the same.

What property is the same after water is boiled and evaporated?
The molecule remain the same.
What is the definition of 'intereference'?
when two light waves of same frequency travel approximately in the same direction have a phase difference that remain constant w.r.to time
