Activity 2 SOUNDS CHALLENGING Direction: Solve problems involving speed, wavelength and frequency of sound waves. Problem #1. Sound waves in air travel at 343 m/s. What is its frequency it is wavelength is 2m? Problem #2. A wave on a guitar string travels at a speed of 340 m/s. Find the wavelength of an "A" note sounding at 400Hz,​

1.

Frequency = Velocity/Wavelenght

Frequency = 343(m/s)/2m

Frequency = 171.5Hz

2.

Wavelenght = Velocity/Frequency

Wavelenght = 340m/s/400Hz

Wavelenght = 0.85m
