Question

What do you understand by R.F? give examples​

Answer 1

Answer:

A representative fraction (RF) is the ratio of distance on the map to distance on the ground. ... An RF of 1:24,000 means one inch on the map equals 24,000 inches on the ground and one centimeter on the map equals 24,000 centimeters on the ground. RFs are easy to determine and to insert in ArcMap

Answer 2

Answer:

Radio frequency (RF) is a measurement representing the oscillation rate of electromagnetic radiation spectrum, or electromagnetic radio waves, from frequencies ranging from 300 GHz to as low as 9 kHz.

Explanation:

Radio frequency waves (RF) are generated when an alternating current goes through a conductive material. Waves are characterized by their frequency and length. ... Radio waves are electromagnetic waves and they travel at the speed of light in free space.
