DRDO Anti-Radiation Missile by the Indian government In February 2016, it was reported that captive flight trials of anti-radiation missile are planned for April–May this year, and the maiden flight test by year–end by the missile technologists of the DRDO. According to DRDO sources, scientists will evaluate the performance of the seeker, navigation and control system, structural capability and aerodynamic vibrations during the captive flight trials. These will be followed by ground testing and the missile will be fired from Sukhoi Su-30MKI during the actual flight trial by year-end. The missile will be inducted in about two years after conducting a number of
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
