Sound waves
- Which of the following ranges corresponds to the longest wavelengths?
- A) infrasonic
- B) audible
- C) ultrasonic
- D) all have the same wavelengths
Solution
Solution Steps
Step 1: Understanding the relationship between frequency and wavelength
Wavelength and frequency are inversely proportional. This means that lower frequency sounds have longer wavelengths, and higher frequency sounds have shorter wavelengths.
Step 2: Comparing sound ranges
Infrasonic sound has the lowest frequency of the three options (infrasonic, audible, and ultrasonic). Audible sounds are the sounds we can hear, and ultrasonic sounds are higher frequency than we can hear.
