Question
The wavelength of infrasound is _______.
-
Less
- More
- Random
- None of these
Hint:
Frequency and wavelength are inversely proportional to each other.
The correct answer is: More
- Infrasound, sometimes referred to as low status sound, describes sound waves with a frequency below the lower limit of human audibility (generally 20 Hz).
- Frequency and wavelength are inversely proportional to each other. The wave with the greatest frequency has the shortest wavelength.
- So Infrasonic sound have low frequency, hence long or more wavelength
