Speed of Sound
The following table shows the approximate speed of sound in air, water, and steel.
Medium Speed
Air 1,100 feet per second
Water 4,900 feet per second
Steel 16,400 feet per second
Create an application that displays a set of radio buttons allowing the user to select air, water, or steel. Provide a text box to let the user enter the distance a sound wave will travel in the selected medium. Then, when the user clicks a button, the program should display the amount of time it will take. Format the output to two decimal places.
Input validation: Do not accept distances less than 0. Always check for nonnumeric data.
Use the following test data to determine if the application is calculating properly:
Medium and Distance Speed of Sound
Air, 10,000 feet 9.09 seconds
Water, 10,000 feet 2.04 seconds
Steel, 10,000 feet 0.61 seconds
