The speed of sound depends on the material the sound is passing through. Below is the approximate speed of sound (in feet per second) for air, water and steel:
air: 1,100 feet per second
water: 4,900 feet per second
steel: 16,400 feet per second
Write a program class The Speed Of Sound that asks the user to enter "air", "water", or "steel", and the distance that a sound wave will travel in the medium. The program should then display the amount of time it will take.
You can calculate the amount of time it takes sound to travel in air with the following formula: time = distance/1,100
You can calculate the amount of time it takes sound to travel in watert with the following formula: time = distance/4,900
You can calculate the amount of time it takes sound to travel in steel with the following formula: time = distance/16,400
Prompts And Output . The program prompts for the medium with: "Enter one of the following: air, water, or steel: " and reads the medium. If the medium is not air, water or steel the program prints the message : "Sorry, you must enter air, water, or steel." an nothing else. Otherwise the program prompts for the distance with ("Enter the distance the sound wave will travel: " and reads it in and then prints "It will take x seconds." where x is the time calculated by your program .
