Assuming the wave-fronts are spreading as the surface of a sphere centred on the source in a homogeneous, unobstructed medium, their amplitudes diminish as the square of the radius from the source.
In decibel terms the loss is 20 Log10(radius in metres) dB.
The intensity of an electromagnetic wave is affected by factors such as the amplitude of the wave, the frequency of the wave, and the distance from the source of the wave.
The relationship between the distance from a source of electromagnetic waves and the electromagnetic wave intensity at that distance is inversely proportional. This means that as the distance from the source increases, the intensity of the electromagnetic waves decreases.
The intensity of a sound wave would increase by a factor of 9 (3^2) if the distance from the source is reduced by a factor of 3. This is because intensity is inversely proportional to the square of the distance from the source.
The amplitude of a wave describes the greatest distance a wave vibrates from its resting position. It is the measure of the height or intensity of the wave.
To increase the intensity of a wave, you can increase the amplitude of the wave, increase the energy of the wave source, or decrease the distance the wave travels from the source. Increasing the number of waves per unit time can also increase the intensity.

height is the intensity, the distance covered by a wave divided by the time it takes is the speed. (ie. short waves = low intensity, fat waves = slow waves)

amplitude of a wave depends on the intensity and goes on decreasing from its mean position
The distance or height of a vibration in a wave is called the amplitude. It represents the maximum displacement of a wave from its rest position. Amplitude is an important characteristic of a wave and affects its intensity and energy.
The amplitude of a wave is the characteristic that describes the greatest distance that a wave vibrates from its resting position. It represents the intensity or strength of the wave.
Intensity decreases when the energy of the wave is spread out over a larger area or when the amplitude of the wave decreases. This can happen due to factors such as distance from the source, absorption by the medium, or the spreading out of the wave as it propagates.
The amplitude of the resulting wave disturbance generally decreases with distance from the source. This is due to energy spreading out over a larger area as the wave travels further, resulting in a reduction in the intensity of the wave. The relationship between amplitude and distance can be described by the inverse square law.
The intensity increases by a factor of 4-APEX
