hello everyone, i'd be really appreciative of some help. i'm doing as physics and have never done proper physics before therefore i'm finding it quite hard. we are doing about waves at the moment and was wondering about a couple of things:-(adsbygoogle = window.adsbygoogle || []).push({});

1st - how to calculate frequency using the time base and a length? eg:- time base 2ms/cm length 5.4 cm, whats the frequency?

2nd - if y cm is the wavelength and Y-amplitude is a x amplitude how do i work out Vmax in volts? eg:- ycm = 5.6, Y-amplidude volt/cm = 5, what is Vmax volts?

3rd - what is the time base?

4th - how to work out the number of cycles using a graph?

Thankyou guys xxx
