The phenomenon where light, sound, or waves bounce back after hitting a surface, creating a return path for the energy.
An involuntary response exhibited by humans or animals to external stimuli, occurring without conscious thought or decision-making.
Example:
目が部屋の明かりを反射したときに彼女の目は輝いた。
Describes a response that occurs instinctively and instantly in reaction to a stimulus, often without conscious thought or control.
Refers to an automatic behavioral reaction triggered by external stimuli, characterized by a lack of deliberate intention or awareness.
Indicates a physiological reaction that is involuntary and unmediated by conscious decision, such as blinking in response to bright light.
Captures the essence of a reflexive action where immediate responses happen as a matter of course in the presence of certain stimuli.
The phenomenon in which light reflects completely without any refraction occurring when it passes from a medium with a higher refractive index to one with a lower refractive index, at an angle greater than the critical angle.
A specific type of reflection that occurs under certain conditions, leading to no loss of light energy as it changes direction entirely within the initial medium.
The condition in which all incoming light is redirected back into its original medium instead of penetrating into another, typically observed in optical fibers and certain aquatic environments.
A physical interaction where light cannot escape a denser medium when the angle of incidence exceeds a particular threshold, resulting in a complete bounce back.
A mirror designed to bounce back light rays, particularly utilized in optical instruments such as microscopes and telescopes.
A type of mirror that manipulates light by reflecting it, commonly found in devices that enhance visual observation.
An optical component that redirects light, commonly employed in scientific tools for magnification and clarity.
In a manner characterized by an automatic or involuntary response, often occurring without conscious thought.
In a way that indicates a learned or instinctual reaction to a stimulus, rather than a deliberate action.
Acting in response to a situation or stimulus based on previously established patterns or habits, without the need for careful consideration.
