Waves Review

Master wave speed, frequency, and wavelength calculations with our practice problems!

Solving for wave speed, frequency, or wavelength You can use this triangle to solve for frequency, wave speed, or wavelength. Sample Problem 1) A wave has a frequency of 15 Hz and a wavelength of 1 m. What is the speed of the wave? Sample Problem 1) A wave has a frequency of 20 Hz and a wavelength of 7 m. What is the speed of the wave?Step 1 - what variable are you solving for?:wave speedStep 2 - what variables do you know?:f = 15 Hzλ = 1 mStep 3 - what equation will you use? :v = f * λStep 4 - Solve!:15 Hz * 1 m= 15 m Sample Problem 2) A wave has a frequency of 10 Hz and a speed of 5 m What is the wavelength of the wave? Sample Problem 2) A wave has a frequency of 10 Hz and a speed of 5 m What is the wavelength of the wave?Step 1 - What variable are you solving for?:wavelengthStep 2 - What variables do you know?:f = 10 Hz v = 5 m 3 - What equation should you use?:λ = v / fStep 4 - Solve!:5 m / 10 Hz= 0.5 m Create a question for the Electromagnetic Spectrum, Waves, and Wave Speed Quiz (Friday).
