- The speed of sound in a solid medium is 15 times greater than that in air. If the frequency of a wave in the solid is 61 kHz, then what is the wavelength? (The speed of sound in air is 344 m/s.)Suppose you hear a clap of thunder 8.20 s after seeing the associated lightning strike. The speed of light in air is 3.00 ✕ 108 m/s. (a) How far are you from the lightning strike? (The speed of sound waves in air is 343 m/s.)4. An observer is standing on the platform of a railway station. A train goes through the station without stopping. If the frequency of the train whistle decreases by a factor of 1/4 as it approaches and then passes him, calculate the speed of the train (assume the speed of sound in air = 343 m/s).
- An enormous thunderstorm covers Dallas-Ft. Worth. Your best friend Clark is a storm chaser and heads to the center of the storm to take some readings while you stay dry at home. While Clark is at the center of the storm, he sees and hears lightning strike a tree that is 150 m from where he is standing. You are 132 km from the tree. How long does it take for the sound to reach Clark? Assume the speed of sound is 343 m/s. How long does it take for the light to reach you? SPorpoises emit sound waves that they use for navigation. If the wavelength of the sound wave emitted is 4.5 cm, and the speed of sound in the water is v = 1530 m/s, what is the period of the sound?The speed of sound in an ideal gas (not air) is 750 m/s at -50°C. What is the speed of sound in the same gas at T = 55°C? The absolute zero temperature is -273.15°C. The speed of sound, cs(T = 55°C) = Units
