Which characteristic is associated with high frequency wavelengths?

• A. Longer sound wave distances
• B. Shorter wavelengths
• C. Lower penetration depth
• D. Increased speed

Answer: (B)

High frequency wavelengths are characterized by shorter wavelengths. This relationship stems from the fundamental wave equation that dictates the speed of a wave, which is the product of its frequency and wavelength. When frequency increases, to maintain a constant wave speed, the wavelength must decrease. For example, in sound waves, high-frequency sounds, like a whistle, have shorter wavelengths compared to low-frequency sounds, like a bass drum. This property is significant in various applications, including music, acoustics, and even in the analysis of electromagnetic waves where shorter wavelengths correspond to higher frequencies. The other characteristics mentioned—longer sound wave distances, lower penetration depth, and increased speed—do not uniquely describe high frequency wavelengths. For instance, higher frequency does not necessarily mean greater distances for sound waves, which can vary based on other factors like medium and environment. Similarly, increased speed pertains more to the medium through which the wave travels rather than the frequency of the wave itself.
