Light Energy
- Visible
- Reflected by mirrors
- Passes through clear glass
- Partly passes through translucent glass
- Does not pass through opaque objects/surfaces
-
Radar energy?
- Non-visable
- Reflected by most opaque materials
- Passes through clear glass
- Passes through translucent glass almost unimpeded
- Passes through most plastics but reflected from most opaque surfaces
