Sound travels through air at 343 m/s, and through fresh water at
1482 m/s. A kid jumps into a lake, which makes a sound wave in air
and in water. After 2.25 seconds, how much farther has the sound
wave traveler in water than in air?

The speed of sound in dry air at 20 ∘C is 343 m/s and the lowest frequency sound wave that a gerbil ear can detect is approximately 56 Hz. What would be the frequency of electromagnetic radiation with the same wavelength? Express your answer to two significant figures and include the appropriate units.

9. The speed of sound was measured in a block of using a sound source and a detector, as shown, The source travels through the block and was detected at the opposite end. From this information, the time interval for the wave to travel the entire length of the block was measured and metal (mass density of 2.700x10 kg/m produced a sound wave that determined to be 8.14x10s seconds. i. Calculate the speed of the sound wave through the metal...
