A wave has frequency of 50 Hz and a wavelength of 10 m. What is the speed of the wave?

• 50Hz / 10m = 5 m/s

• 10m / 50Hz = 0.5 m/s

• 50Hz x 10m = 500 m/s

• 50Hz x 10m = 50m

A wave has frequency of 5 Hz and a speed of 25 m/s. What is the wavelength of the wave?

• 25m/s / 5Hz = 5m

• 25m/s x 5Hz = 125m

• 5Hz / 25m/s = 0.2m/s

• 25m/s / 5Hz = 5s

A wave has wavelength of 10 m and a speed of 340 m/s. What is the frequency of the wave?

• 10m / 340m/s = 0.029s

• 340m x 10m/s = 3400Hz

• 340m/s / 10m = 34Hz

• 340m/s / 10 m = 34s
