1. A guitar string vibrates with a frequency of 100 Hz and it has a wavelength of 3 cm. Determine the speed of the wave that goes through that guitar string.
2. The speed of sound waves in air is around 340 m/s. Suppose that you hear a dog growl, and the frequency of the growl is 70 Hz. Determine the wavelength of the growl sound waves.
3. You are in a boat on the ocean. Some waves come by and you feel your boat move up and down. You whip out a stopwatch and find that you go up-and-down once every 5 seconds. So, the period of the wave is 5 s. You are watching the waves as you go up-and-down, and you see that the wave crests are 15 meters apart. So, the wavelength is 15 m. Use this information to calculate the speed of the waves.
4. Explain why these two waves have the same speed, even though some of their wave properties are different.
Wave A has a frequency of 3 Hz and a wavelength of 5 m
Wave B has a frequency of 6 Hz and a wavelength of 2.5 m
