  1. Question 1

    Q1. A sound wave travels through air at 20°C with a speed of 343 m/s. If its frequency is 500 Hz, find its wavelength.

    • A) 0.5 m
    • B) 0.686 m
    • C) 1.0 m
    • D) 1.2 m

    Answer: 0.686 m

    Explanation: Wavelength = speed / frequency = 343 m/s / 500 Hz = 0.686 m. Option A is incorrect due to incorrect calculation.
