<span>If the amplitude of the resultant wave is twice as great as the amplitude of either component wave, and this wave exhibits reinforcement, the component waves must BE IN PHASE WITH EACH OTHER</span>
This question seems to really be incomplete. You must include the options but fortunately I have already encountered this problem. Here are the choices:
<span>A. have a different frequency than the resultant wave. B. be in phase with each other. C. be traveling in the opposite direction of the resultant wave. D. have a different wavelength than the resultant wave
The correct answer is letter B. be in phase with each other</span>
Answer is Global Warming causes destruction of our ecosystem due to increased temperatures, drought, fire, weed and pest infestations, more intense storms, water shortages, melting ice caps and glaciers, air pollution.
