DRDO Anti-Radiation Missile DRDO Anti-Radiation Missile The DRDO Anti-Radiation missile is a tactical, air-to-surface anti-radiation missile under development by India's Defence Research and Development Organisation. It is designed primarily to destroy enemy radars and communication facilities. This is a state-of-the-art air-to-surface anti-radiation missile being developed by Defence Research and Development Laboratory of the DRDO. The range of the missile is believed to be 100–125 km and it will be mounted on the combat aircraft of the IAF such as Sukhoi Su-30MKI and Tejas Light Combat Aircraft. The entire missile is being developed indigenously, including the seeker. According to the then Director of RCI,
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
