Calculations may be done in pencil, but answers in the blanks should be in ink. 1. Find the wavelength of sound with a frequency of 365Hz when it is traveling with a speed of 1230m/s. 1A 2. What is the frequency of a sound wave with a wavelength of 6.6m traveling at 350m/s? 2 3. A gun is fired 2.0km away from a mountain. The sound of the shot travels at 340m/s. A) A) How long will it take the person who fired the gun the hear the echo? B) What was the wavelength of the sound if the frequency was 150Hz? 3.a ) 3.b) 4. The whistle on a train has a frequency of 440Hz. The train is moving at 35m/s toward a person standing on the platform.
