Explain how a stationary wave is produced when a string fixed at both ends is plucked
When the string is plucked, waves will travel from the point where it was plucked to the fixed ends, which cannot move and so must be nodes. The waves will reflect, and the superposition of the reflected and original waves will cause some positions to always have zero displacement (nodes) and some positions to oscillate at maximum amplitude (antinodes).
