I cant take the test. I don't know any of the words and I tried to study but I'm still confused
Well if your still confused then I can give you tutor lesson.
Ok so first we are going to start with a vocab sheet that has all the definitions.
Wave Motion: a form of carrying energy. Medium: any substance that a wave travels through. Mechanical Waves: waves that travel through a medium. Electromagnetic Waves: waves that don't need a medium to travel Wave Crest: highest point on wave. Wave Trough:lowest point on a wave. Wave Amplitude:height from line of origin to a crest or trough. Wavelength: distance between 2 points on a wave. Frequency: the number of waves that cross a given point in a given time. Wave Speed:Frequency times wavelength equals wave speed.
Oh ok I get it now ,I think I'm ready to take the test.
