I learned that standing waves form when the incident wave's frequency is equivalent to the reflected wave's frequency. But I also learned that according to Newton's 3rd law, when a wave hits a boundary, the reflected wave continues to travel in the opposite direction but has equal frequency and...

Homework Statement We measured 2 values and were asked to calculate their average using sig fig The two values were: 1.56324 N and 1.13405 N. ( 1.56324 N + 1.13405 N ) / 2 = 1.348645 N Would the answer be 1.34865 N or 1 N? (Someone told me that we only use the sig figs of measured values...
