Martel (missile) Martel (missile) The Martel is an Anglo-French anti-radiation missile (ARM). The name Martel is a contraction of "Missile, Anti-Radiation, Television", referring to the guidance options. There are two variants, the passive radar guided (AS 37) and the video guided (AJ 168). The aircraft that used these missiles were the Blackburn Buccaneer (up to three TV or four ARM variant), the SEPECAT Jaguar (two), the Mirage III/F1 (one or two), and the Hawker Siddeley Nimrod (at least one). The Martel was suited to anti-ship attack with its long range and heavy warhead. There was not, at the time, a small radar
Refraction of incidence "θ" and angle of refraction "θ" is equal to the ratio of phase velocities ("v" / "v") in the two media, or equivalently, to the indices of refraction ("n" / "n") of the two media. Optical prisms and lenses utilize refraction to redirect light, as does the human eye. The refractive index of materials varies with the wavelength of light, and thus the angle of the refraction also varies correspondingly. This is called dispersion and causes prisms and rainbows to divide white light into its constituent spectral colors. Consider a wave going from one material to another where
