Question 5 The diagram below shows a circle centre M passing through the points R, P, Q and T.
RT is the diameter. PQ is a chord such that PQ | RT and MN 1 PQ
PQ = 16 units, MN = 6 units
R
:)
T
3)
Determine the length of RT​

Identify the theory that can be used to explain each phenomenon. answers diffraction: wave theory interference: wave theory reflection: both particle and wave theories refraction: both particle and wave theories
