Theresa comes up with four examples of waves: sound wave, ocean wave, light wave, and hand wave. which of theresa'as examples is not an actual scientific wave? sound wave ocean wave light wave hand wave

Definitely, sound wave, ocean wave and light wave are scientific wave. They are studied by physics which aims to describe their behavior and try to make predictions about them: the energy transported, the velocity, the amplitude, the wavelength, the frequency, and some phenomena related. Hand wave is not the object of study of any scientific discipline. It is just referred a social custom.
