Which type of waves have a higher frequency than the human ear can perceive?

Ultrasonic waves are indeed the type of waves that have a frequency higher than what the human ear can perceive. The audible range for humans typically spans from about 20 Hz to 20 kHz. Frequencies above 20 kHz fall into the ultrasonic category. These high-frequency sound waves are commonly used in various applications, including medical imaging (ultrasound) and cleaning devices, due to their ability to penetrate materials and provide detailed information.

In contrast, subsonic waves refer to sound waves that are below the range of human hearing and do not exceed 20 Hz. Infrasonic waves are specifically sound waves that are also below the audible range and are typically below 20 Hz.

Audible waves, as the name suggests, are those that fall within the frequency range detectable by the human ear (20 Hz to 20 kHz), which means they do not have frequencies higher than what humans can perceive.

Thus, ultrasonic waves stand out as the only option that represents frequencies beyond human hearing capability, confirming its accuracy in this context.
