BOUNCING RADIO WAVES

E&MP 103.042

Radar

August 15-20, 1945

James Stokley of General Electric uses a sheet-iron backed photo of a destroyer and laboratory equipment to demonstrate the radio-wave reflection principle of radar.

The equipment at the left sends out ultra-short radio waves which are reflected by objects in their path and in this demonstration are made to light a lamp.

Radar can "search" for many miles - the exact distance must remain a military secret.
