Elements Of Remote Sensing If flying height of a spacecraft is H, the length of air base is B and the parallax difference between two points is dp, then the difference in height h = dp/(H/B) h = (H/B) dp h = (B/H) dp h = dp/(B/H) h = dp/(H/B) h = (H/B) dp h = (B/H) dp h = dp/(B/H) ANSWER DOWNLOAD EXAMIANS APP
Elements Of Remote Sensing "An Electromagnetic wave falls on to a boundary between two losses less homogeneous media with different refractive indices, a part of the wave is reflected back to the incident medium and the rest is transmitted on to the second media". This phenomenon is known as: Snell's law Fresnel refraction Fresnel reflection None of these Snell's law Fresnel refraction Fresnel reflection None of these ANSWER DOWNLOAD EXAMIANS APP
