Amplitude and wavelength are properties of various types of waves, including sound waves, electromagnetic waves (such as light waves), and water waves.
Sound Waves: Sound waves are mechanical waves that require a medium to propagate, such as air, water, or solids. They have both amplitude and wavelength. The amplitude of a sound wave represents the maximum displacement of particles in the medium from their equilibrium position as the wave passes through. The wavelength of a sound wave is the distance between two consecutive points in the wave that are in phase, such as two compressions or two rarefactions.
Electromagnetic Waves: Electromagnetic waves, such as light waves, do not require a medium for propagation and can travel through a vacuum. These waves also have amplitude and wavelength. The amplitude of an electromagnetic wave represents the maximum strength of the electric and magnetic fields as the wave oscillates. The wavelength of an electromagnetic wave is the distance between two consecutive points in the wave where the electric and magnetic fields have the same phase.
Water Waves: Water waves, specifically surface waves on bodies of water, also have amplitude and wavelength. The amplitude of a water wave represents the maximum height of the wave crest or depth of the wave trough relative to the undisturbed surface level. The wavelength of a water wave is the distance between two consecutive wave crests or wave troughs.
As for your question about "wave-depth," it is not a common term used to describe wave properties. However, it's worth noting that in the context of water waves, the depth of the water can influence the behavior and characteristics of the waves. The depth of the water affects the speed at which the waves propagate and can cause changes in their amplitude and wavelength. But "wave-depth" itself is not a standard term used to describe a specific property of waves.
