Where does the energy of a wave go when the amplitude of the wave decreases?

If the amplitude decreases the energy in the wave also decreases. The energy that was in the wave before the amplitude was decreased will have been absorbed into the surroundings, be they physical objects in the case of sound waves, or an electrical circuit or light absorbing material, to suggest a few different cases.

What happens to the period of a wave when the frequency decreases?
The period and frequency of a wave are inversely related, i.e. the period is the time it takes for wave to go through a cycle, and the frequency is the number of cycles in a certain time period. For example, a wave with a period of 0.5 seconds would have a frequency of 2 per second. Since these properties are the inverse of each other, than they will be opposite when changing. If the period decreases (i.e. gets shorter, faster) than the frequency increases. Or vice versa.
Why is an energy pyramid shaped as a pyramid?
This is because the farther up you go in the energy pyramid the energy decreases.
What happens to sound when Temperature decreases?
The pitch of sound decreases and the speed of sound will increase. These effects are because of the increased density of the medium. This applies to most materials: only in rare occasions does the density of a material decrease with a decrease in temperature (iron, when it changes temperature at some points, for example), resulting in the opposite effect (ask for the opposite). If the temperature goes down, the pitch of woodwind instruments go down too, but the pitch of string instruments go up.
If the energy of a wave goes up does the frequency go down?
As the energy of a wave goes up, the frequency goes UP
What happenes to the wavelength of a wave when the frequncy decreases?
If the waves become less frequent (frequency decreases), assuming the velocity stays the same there must, logically, be more distance between each wave passing. i.e. the length of each wave must be longer. or, put another way, the wave length must have increased if less waves go past.
Componet of electromagnetic waves that varis?
There frequency is inversely proportional to there wave length. There energy level go on reducing as there frequency decreases.

Why is sound not heard from a long distance?
Sound is a compressional wave , i.e , pressure. you do understand that pressure is F/A.Thus when A increases the pressure decreases. Now sound waves looks like a circle where its center is the origin of the sound and the circle gets bigger as we go further from its center this means that the area covered increases and the sound compressional waves ( pressure) decreases. Distance effects sound because sounds moves by bumping into other particles and momentum is lost every time they bump because it creates heat and so one

How does energy associated with waves change as wavelength changes?
Using this equation will help you understand what is going on: E=hc/wavelength h and c are constants. As wavelength increases, energy decreases. This is why UV radiation (which has a very small wavelength) has more energy than visible radiation, and this is also why UV radiation causes damage to living things
If the energy of a wave goes up does the frequency go down?
As the energy of a wave goes up, the frequency goes UP
In a sound wave why does the vibrations and energy transfer go in the same direction?
A sound wave is a longitudinal wave.thus the vibratoins and energy transfer go in the same direction
What happens when waves go from deep water to shallow water?
When a wave goes from deep water to shallow water, it decreases in size and strength. This is because shallow water does not have the required power to transmit the wave, and so its velocity decreases.
Explain why temperature in the troposphere gradually decreases with increasing attitude?
as we know that energy is associated with matter i.e. energy cannot be present without matter but matter can be without energy. as we go up in atmosphere density decreases mass also decreases due to which most of the energy escapes
As we move along the food chain does the energy increase or decreases and why?
Energy decreases as we go up the food chain because there are less organisms as we go up, so that the ecosystem doesn't run out of food at the bottom of the chain.
How does ionization energy of elements in the same period change?
Ionization energy increases as you go across a period, but as you go down a group it decreases.
