The wavelength of sound made from a tuning fork of frequency 330 Hz is nearly:
Correct answer: D. 1m
- A. 330m
- B. 100m
- C. 10m
- D. 1m
Explanation
Therefore, the correct option is "1m" as it represents a reasonable wavelength for audible sound produced by a tuning fork of frequency 330 Hz. The wavelength of sound can be calculated using the formula: wavelength = speed of sound / frequency.

About Speed of Sound
The speed of sound depends on the properties of the medium, including its elasticity and density, and in gases it varies mainly with temperature. Questions connect speed with frequency and wavelength, compare sound in solids, liquids and gases, and distinguish the speed of propagation from the oscillating particles' motion.
