Rayleigh distance Rayleigh distance Rayleigh distance in optics is the axial distance from a radiating aperture to a point at which the path difference between the axial ray and an edge ray is λ / 4. An approximation of the Rayleigh Distance is formula_1, in which Z is the Rayleigh distance, D is the aperture of radiation, λ the wavelength. This approximation can be derived as follows. Consider a right angled triangle with sides adjacent formula_2, opposite formula_3and hypotenuse formula_4. According to Pythagorean theorem, formula_5. Rearranging, and simplifying formula_6 The constant termformula_7 can be neglected. In antenna applications, the Rayleigh distance is
The Sound of Sunbathing and "Big Hits, Skinny Ties: New Wave in the U.K". "Trouser Press" praised the Sinceros for creating "two great tracks — a quirky bit of silliness called 'Take Me to Your Leader' and a Joe Jackson soundalike, 'Little White Lie'..." but expressed little enthusiasm for the album as a whole, saying that other than those two songs, "it's an amiable pop record with little character".
