What it is Filled
The phenomenon of a propagating wave, such as light or sound, being thrown back from a surface; governed by the law that the angle of incidence equals the angle of reflection for specular reflection.
Why it exists Filled
Let an agent handle reflection by wave type, surface, law, applications and hazards such as glare.
Distinguishing features Filled
- Wave returns from a surface
- Angle of incidence equals angle of reflection
- Depends on surface and material
- Occurs for light, sound and radio
What robots and AI may and may not do Filled
Must not
- Design or site a reflective surface so that it throws glare onto roads, flight paths or homes.
- Advise on curved or concentrating reflective surfaces without accounting for focused heat.
- Give guidance on directing or reflecting a laser beam toward people, vehicles or aircraft.
- Dismiss reported glare or echo complaints without measurement.
Only with a human decision
- Approving a facade, mirror or acoustic treatment that affects neighbours or traffic.
May
- Explain and compute reflection geometry for light or sound in a stated setting.
- Assess glare and acoustic reflection in a design from measured or modelled data.
Moral aspects Filled
- Glare from buildings and vehicles blinds drivers and pilots and has caused crashes.
- Concentrated reflected sunlight has damaged property and injured people.
Who is affected
- Drivers, pilots and pedestrians
- Neighbours of reflective buildings
- Building occupants
Owners Filled
Steward
The owner or designer of the reflecting surface; building authorities set the rules.

Identity and identifiers required Filled
- Vercy registry: vr.tr.reflection
- Open English WordNet: oewn-11523478-n
Direct properties required Filled
- Angle of reflection: degrees - Measure the reflected propagation direction relative to the surface normal for a specified incident wave.
- Power reflectance: dimensionless - Measure reflected power divided by incident power under specified wavelength, angle and polarisation conditions.
- Reflection phase shift: radians - Measure the phase difference between reflected and incident waves at a defined reference surface.
Recognition required Filled
- Mirror images and virtual images
- Specular versus diffuse
- Reflection as thought is a different sense
- Mirror images, glints, echoes and bright surfaces.
Capabilities and actions required Filled
- explain the law of reflection
- distinguish specular and diffuse reflection
- reduce glare and echoes
- use reflectance values in design
Hazards and failure modes required Filled
- Glare causing accidents
- Concentrated sunlight from curved glass
- Laser reflections harming eyes
Standards and interfaces required Filled
- Lighting design standards on glare
- Building acoustics standards
Context of use required Filled
- Mirrors, optics, acoustics, radar and seeing objects.
- specular reflection
- diffuse reflection
- total internal reflection
- acoustic reflection and echoes
- interreflection
