Answer:
1. the wavelength is ( 3 )
2.the wave length long is ( 2 )
3.the wavelength is ( 2 )
4.the wave ( 2 )
5.wave ( 1 ) and wave ( 2 )
6. the rate at which a vibration occurs that constitutes a wave, either in a material (as in sound waves), or in an electromagnetic field (as in radio waves and light), usually measured per second.
7.waves with a high frequency have a short wavelength, while waves with a low frequency have a longer wavelength.
