When considering sound waves, what is a higher frequency wave likely to exhibit?

• A. Longer wavelength
• B. Higher amplitude
• C. Higher speed
• D. Shorter wavelength

Answer: (D)

A higher frequency wave is characterized by a shorter wavelength. This relationship between frequency and wavelength is governed by the wave equation, which states that the speed of a wave is equal to the frequency multiplied by the wavelength (Speed = Frequency × Wavelength). Therefore, as the frequency of a wave increases, the wavelength must decrease in order to maintain a constant speed, which is often the case in a given medium. In the context of sound waves, as the frequency increases, the corresponding wavelength decreases, enabling higher frequency sounds to carry more detailed information and be perceived differently by human hearing. This principle is vital in various applications, including ultrasonic testing where different frequencies can be utilized for different testing purposes, affecting the detection of flaws in materials. Understanding this relationship is fundamental in the fields of acoustics and nondestructive testing.
