total distance travel by the red spot is 4 times of Amplitude
Given:
A transverse wave on a string has an amplitude "A". A tiny spot on the string is colored red.
To find:
Distance travelled by red spot in one cycle of the wave.
Solution:
So, we know that particles in a transverse wave oscillate periodically in a direction perpendicular to propagation of wave.
Frankly speaking, the type of motion shown by particles is SHM (simple harmonic motion)
So, in a wave cycle, the red dot will start from a particular position and will end at the same position.
Let's assume that the red coloured part started from mean point. So, it will go to one extremity return back to the other extremity and finally end at the mean position.
So, it traverses a distance 4 times of the Amplitude.
