  • C 170 Hz ✔ ✖
  • D 0.5 Hz ✔ ✖
Correct Answer: Option C

Explanation

Answer: c) 170 Hz

Explanation: The frequency of a sound wave can be calculated by dividing the speed of sound by the wavelength. In this case, 340 m/s ÷ 1 m = 340 Hz. However, this is the frequency of a wave with a wavelength of 1 meter. To find the frequency of a wave with a different wavelength, we need to use the formula f = v/λ, where f is the frequency, v is the speed of sound, and λ is the wavelength. In this case, f = 340 m/s ÷ 2 m = 170 Hz.
