“Fine tuning” A Level Required Practical 1 – Investigation into the variation of the frequency of stationary waves on a string with length, tension and mass per unit length of the string.
Seriously grappling with physics assessment today;
AT – a
Use appropriate analogue apparatus to record a range of measurements of length and to interpolate between scale markings
AT – b
Use appropriate digital instruments, to obtain a range of measurements time
AT – c
Use methods to increase accuracy of measurements in timing over multiple oscillations.
AT – i
Generate and measure waves using a vibration transducer
