What wave can be detected by the ear?

Sound waves are the type of waves that can be detected by the ear.

Sound waves are mechanical waves that travel through a medium such as air, water, or a solid. When an object vibrates, it sets the surrounding air molecules into motion, creating a series of compressions and rarefactions. These pressure waves propagate through the air until they reach the ear, where they are converted into electrical signals and interpreted by the brain as sound.

Humans can hear sounds within a certain frequency range. The lower limit of human hearing is about 20 hertz (Hz), and the upper limit is about 20,000 Hz. The average human can hear sounds between 20 and 16,000 Hz.

Sound waves can vary in frequency, amplitude, and phase. Frequency determines the pitch of a sound, amplitude determines the loudness of a sound, and phase determines the timbre of a sound.
