Question: A tuning fork produces a sound wave with a frequency of 440 Hz. What is the wavelength of the sound wave in air, given that the speed of sound in air is approximately 340 m/s?

Options:

1. 0.77 m
2. 0.85 m
3. 0.90 m
4. 1.00 m

Correct Answer: 0.77 m

Solution:

Wavelength λ is given by the formula λ = v/f. Here, v = 340 m/s and f = 440 Hz. Thus, λ = 340/440 = 0.7727 m, approximately 0.77 m.
