I am wondering why the higher order (higher harmonics) standing waves developed on a string under tension generated by an oscillating mechanical vibrator (set at the same amplitude but with variable frequency) have

**when compared to the lower harmonics (the fundamental has the highest amplitude)...What are the equations explain this fact?**

__lower amplitude__Also, it is easy to notice that when the string tension is low, the amplitude of all modes is larger compared to when the tension is larger. Smaller tension means smaller wave speed, etc. but I cannot find equations that justify the different amplitude with different tension ##T##...

Thanks as usual!
