Waves

The speed of a wave is determined by the wavelength and frequency of the wave. Wave speed equals wavelength times frequency. What will happen when the frequency increases? If a wave has a frequency of 10 Hz and a wavelength of 2 m the speed of the wave will be 20 m/s. If the frequency is increased to 20 Hz with the wavelength of 2 m than the speed will increase to 40 m/s. If the wavelength increases the speed will also increase.
