That means that in the relation considered, any object relates to itself: For any "x", relation(x, x) is true. For example, this is a property of equality (any number is equal to itself), of congruence (any object is congruent to itself), and to relationships such as greater-than-or-equal (any number is greater than or equal to itself) and the non-strict subset relation (any set is a subset of itself).

What is an example of a reflective relation?
A reflective relation is one where the relation holding between A and B implies that the relation also holds between B and A 'sibling' is a reflective relation.

How do laser tag beams show up in black lights and how can i modify my toy guns to do the same?
The ability to see laser beams has nothing to do with black lights. Lasers need a reflective property in order to be seen by the human eye. Often times, the reflective property is a simulated fog in laser tag arenas. Something as simple as air freshener can be used as a reflective property in order to see a laser beam.

Is Luster an Extensive or Intensive?
Luster is an intensive physical property because it does not depend on the amount of the substance present. It describes how shiny or reflective a material appears.
What property of sound leads to the formation of echo?

What do reflective materials have in common?
Reflective materials have the property of bouncing back light that falls on them, increasing visibility and improving safety in low-light conditions. They are often used in various applications, such as traffic signs, safety clothing, and bicycle reflectors, to enhance visibility and reduce the risk of accidents.
