What is sound speed in air?
Think about room temperature in air.
What state of matter is required for sound to travel?
Remember the types of media.
What is the measure of sound speed in air at room temperature?
Refer to the speed of sound in air.
True or False: Sound travels fastest in air.
Think about how particle density affects speed.
A sound wave travels through various mediums: air (343 m/s), water (1482 m/s), and steel (5000 m/s). If it takes 2 seconds to travel a distance of 2000 meters in steel, what is the delay when traveling the same distance in air?
Use the speed formula to find time in each medium.
If the temperature in air increases from 20°C to 40°C, calculate the new speed of sound. Using the formula v = 331 + 0.6*T, what would the new speed be?
Substitute the new temperature into the speed formula.
