The John William Strutt, Lord Rayleigh Medal and Prize is an award of the UK-based Institute of Physics (IOP) for "distinguished contributions to theoretical (including mathematical and computational) physics". The award, named in honour of Lord Rayleigh, consists of a medal with ã1,000 and a certificate.
The John William Strutt, Lord Rayleigh Medal and Prize (established in 2008) should not be confused with the Rayleigh Medal, which was established by the Institute of Acoustics in 1970.
