Where does the relationship Energy is proportional to Amplitude squared come from?
Joshgeurts7
In case of simple harmonic motion the velocity max at the equilibrium will be a w
Here w (omega) is the angular frequency = 2 pi nu (frequency)
Now kinetic energy E = 1/2 m v^2 = 1/2 * m * a^2 * w^2
Here a is amplitude.
So energy seems proportional to the square of amplitude

This relationship comes from the energy conservation principle in wave mechanics. For a wave, the energy is proportional to the square of the amplitude because energy is a scalar quantity and is directly related to the square of the wave's amplitude. This relationship holds for various types of waves, including electromagnetic waves and sound waves.

What is the relationship between a waves energy and its amplitude?
The energy of a wave is directly proportional to the square of its amplitude. This means that as the amplitude of a wave increases, its energy also increases exponentially. Conversely, decreasing the amplitude of a wave will result in a decrease in its energy.
Is a wave amplitude is directly proportional to the energy applied?
Yes, in general, the amplitude of a wave is directly proportional to the energy applied. This means that the higher the energy applied, the greater the amplitude of the wave.
Does amplitude determine the energy of a wave?
No, amplitude does not directly determine the energy of a wave. The energy of a wave is determined by its frequency and amplitude together. A wave with higher amplitude carries more energy, but it also depends on the frequency of the wave.
What is the relationship between the amplitude of a sound and its energy of vibrations?
The amplitude of a sound wave is directly proportional to the energy of vibrations. A sound with higher amplitude has more energy and is perceived as louder, while a sound with lower amplitude has less energy and is perceived as softer.
How are a wave's energy and the wave's amplitude related?
The energy of a wave is directly proportional to the square of its amplitude. This means that as the amplitude of a wave increases, its energy also increases quadratically. A wave with greater amplitude carries more energy.

What property of a wave is directly proportional to its energy?
The amplitude of a wave is directly proportional to its energy. Higher amplitude waves carry more energy than waves with lower amplitudes.

What is amplitude squared?
Amplitude squared is the amount of energy in a wave. The simplest calculations would be for a string wave.
How does the amplitude affect the energy of a wave?
The intensity will increase if the energy increase. The intensity is proportional to the square of the amplitude of a wave.
What happens to the energy in a seismic wave as the wave grows larger?
As a seismic wave grows larger, the energy it carries remains constant. The amplitude (height) of the wave increases, but the total energy the wave carries does not change. The energy is redistributed within the wave to accommodate the larger amplitude.
Doubling the amplitude of a wave causes its energy to .?
