The intensity of light waves is a measure of the energy that is carried by the waves. Light waves are electromagnetic waves.
Intensity is proportional to the square of the amplitude of vibration in case of mechanical wave such as sound waves But in case of light which is electromagnetic in nature, the intensity is the number of photons crossing unit area in one second
The amplitude of the sound waves decreases as the intensity decreases.
Intensity = Power / Cross sectional area

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)

The measure of the intensity of a wave is referred to as its amplitude.
The amplitude of the sound waves decreases as the intensity decreases.
