Question

A radiometer’s single detector has an opening of 2.5 milli-radians and an altitude of 4 km. Calculate the diameter of the radiometer

Answer 1

Answer #1

Solution) Diameter of radiometer = 10 meters

Explanation:

Diameter of radiometer = angle of opening*altitude

Angle of opening = 2.5 milliradians = 0.0025 radians

Altitude = 4 KM = 4000 meters

Diameter of radiometer = 0.0025*4000 = 10 metres
