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: Fresnel reflection Snell's law None of these Fresnel refraction Fresnel reflection Snell's law None of these Fresnel refraction ANSWER DOWNLOAD EXAMIANS APP
Elements Of Remote Sensing If θ is the angle of scan measured from the nadir, the ground distance swept by the sensor IFOV is proportional to: cos²θ sin²θ tan²θ sec²θ cos²θ sin²θ tan²θ sec²θ ANSWER DOWNLOAD EXAMIANS APP
Elements Of Remote Sensing Due to scan geometry of a satellite sensor: The off-nadir resolution is degraded All of these The ground distance swept by the senor, IFOV is proportional to sec2θ, where θ is the angle of scan measured from the nadir The details towards the edge of the scan get compressed The off-nadir resolution is degraded All of these The ground distance swept by the senor, IFOV is proportional to sec2θ, where θ is the angle of scan measured from the nadir The details towards the edge of the scan get compressed ANSWER DOWNLOAD EXAMIANS APP
