Question

A RADAR spots an enemy plane. A radio pulse emitted by the radar and reflected by the
plane reaches back in 2x10-4
s. Find the distance between the enemy plane and RADAR.
(Speed of radio pulse = 3x108
s)

Answer 1

Explanation:

A radar spots an enemy plane. aradio pulse emitted by radar and reflected by the plane reaches back in 0.5 X 10-3sec. What is the distance of the plane from the radar station? {take speed of radar pulse = seed of light = 3 X 108 m/s2}
