Which information shows the longest wavelength? speed = 700 m/s and frequency = 350 hz speed = 300 m/s and frequency = 100 hz speed = 1,000 m/s and frequency = 1,000 hz

The longest wavelength is 3 m when speed of wave was 300 m/s and frequency was 100 hertz.

Explanation:

Wavelength is equal to ratio of speed of the wave to the frequency of the wave.

1)  Speed = 700 m/s and frequency = 350 Hz =

Wavelength of the wave:

2)  Speed = 300 m/s and frequency = 100 Hz =

Wavelength of the wave:

3)  Speed = 1,000 m/s and frequency = 1,000 Hz =

Wavelength of the wave:

The longest wavelength is 3 m when speed of wave was 300 m/s and frequency was 100 hertz.
