Answer:

eqn: speed = wavelength * frequency

What is the wave speed of a wave that has a frequency of 100 Hz and a wavelength of 0.30 m?

speed = 0.3*100 = 30m/s

What is the wave speed of a wave that has a frequency of 50 Hz and a wavelength of 0.10 m?

speed = 0.1*50 = 5m/s

What is the frequency of a wave that has a wave speed of 20 m/s and a wavelength of 0.50 m?

frequency = 20/0,5 = 40Hz

What is the frequency of a wave that has a wave speed of 80 m/s and a wavelength of 0.20 m?

frequency = 80/0.2 = 400Hz

What is the frequency of a wave that has a wave speed of 120 m/s and a wavelength of 0.40 m?

frequency = 120/0.4 = 300Hz

What is the wavelength of a sound wave that has a speed of 340 m/s and a frequency of 440 Hz?

wavelength = 340/440 = 0.7727m

What is the wavelength of a sound wave that has a speed of 340 m/s and a frequency of 880 Hz?

wavelength = 340/880 = 0.3864m

What is the wavelength of a sound wave that has a speed of 250 m/s and a frequency of 400 Hz?

wavelength = 250/400 = 0.625m

What is the wave speed of a wave that has a frequency of 50 Hz and a wavelength of 2.0 m?

speed = 2*50 = 100m/s

What is the wave speed of a wave that has a frequency of 100 Hz and a wavelength of 0.50 m?

speed = 0.5*100 = 50m/s
