Question Answer Marks

1 Defining the problem

A is the independent variable and f is the dependent variable or vary A and measure f 1

keep M constant 1

Methods of data collection

labelled diagram of workable experiment including: 1
• elastic cord fixed at one end to a support
• other end passed over a pulley
• labelled pulley
• labelled load

vibrator connected to signal generator 1

increase/decrease the frequency of the signal generator until stationary wave pattern is observed 1

measure diameter of cord with micrometer/calipers 1

Method of analysis

plot a graph of f 2 against 1 / A or equivalent (e.g. lg f against lg A) 1

relationship valid if a straight line passing through the origin is produced 1
(for lg f against lg A, relationship valid if a straight line with gradient –½)

M 1
k=
gradient × 4 × L2

(for lg f against lg A, k = M / [10(2 × y-intercept) × 4 × L2] )

Question Answer Marks

1 Additional detail including safety considerations 6

D1 use safety goggles/safety screen to prevent injury to eyes from (moving) elastic cord/load
or
use cushion/sand box in case load falls

D2 keep L constant

D3 use cords of the same material/density

D4 use CRO to determine f (or T)

D5 method to determine T from CRO, e.g. period = time base × length of one wave

D6 f = 1/T

D7 repeat measurement of diameter along cord and average

πd 2
D8 use of A =
4

D9 measure mass of the load on top-pan balance

D10 detail on determining frequency at the maximum amplitude, e.g. increase frequency until the amplitude starts to
decrease, then decrease frequency
