Thanks for the replies, sorry it has caused tension in this debate about my vague question, the derivative of an equation is the gradient simple really... and its a her not a he plus what other answers other than the change in y and x, could there be on a graph??

is this using Newtons 3rd law, that when a force acts on something, it will then have an equal force exerted back onto it? so the centripetal force keeping the mass in orbit, has an equal force (the tension) to the centripetal force in the string?

excluding the answer of centrifugal forces, why is there a tension in a piece of string with a mass attached on the end, going in a HORIZONTAL circular movement, when the mass is always accelerating towards the centre anyway??

how do you calculate the rate of change in a graph?? is it just the gradient??

waves sound waves are parallel to the direction of travel so there longitudinal light waves are perpendicular to direction of travel, they oscillate at right angles to each other. - Transverse

Are they both electomagnetic?? Sound waves are caused by vibrations of particles but can act like emwaves do. for example diffraction patterns, showing up constuctive and destuctive waves by loud spots and quiet spots.

No I am thinking of when a particle is set into vibration, what the frequency is called when it has a maximum amplitude

Does anybody know the name given to the frequency at which an object vibrates with maxium amplitude??
