In physics terms, a standing wave is commonly defined as a wave formed by the interference of waves comprising identical frequencies. In addition, it also has is nodes wherein the wave is at its minimum amplitude. Therefore, the answer would be " identical waves, same direction same medium."

Answer from: ronaldo22

Identical waves, opposite direction, same medium

Explanation:

Standing waves are formed when two waves having same frequency move in opposite direction in the same medium. The two identical waves interfere in such a manner that the resultant wave oscillates in time but not in space. The resultant wave has minimum amplitude at node and maximum amplitude at antinode.

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge, $v = \dfrac{e_p}{q}$ then the following gives us the potential difference, $\delta v = v_b - v_a$ $\begin{aligned} \delta v & = \dfrac{e_p_b}{q} - \dfrac{e_p_a}{q} \\ & = \dfrac{\delta e_p}{q} \end{aligned}$ the formula $\delta v = \delta e_p / q$ may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get $\delta e_p = q\delta v$ using q = 8.00 × 10⁻¹⁹ c and δv = 2.00 v, we get $\begin{aligned} \delta e_p & = (8.00\times10^{-19} \text{ c})(2.00\text{ v}) \\ & = 1.60\times 10^{-18}\text{ j} \end{aligned}$ the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.
