Ice–albedo feedback is a climate change feedback, where a change in the area of ice caps, glaciers, and sea ice alters the albedo and surface temperature of a planet. Because ice is very reflective, it reflects far more solar energy back to space than open water or any other land cover. [1] It occurs on Earth, and can also occur on exoplanets.
Infinity mirror. The infinity mirror (also sometimes called an infinite mirror) is a configuration of two or more parallel or angled mirrors, which are arranged to create a series of smaller and smaller reflections that appear to recede to infinity. [1] [2] Often the front mirror of an infinity mirror is half-silvered (a so-called one way ...
Reflective practice. Reflective practice is the ability to reflect on one's actions so as to take a critical stance or attitude towards one's own practice and that of one's peers, engaging in a process of continuous adaptation and learning. [1] [2] According to one definition it involves "paying critical attention to the practical values and ...
Social identity threat. Politics. Identity politics. v. t. e. Self-reflection is the ability to witness and evaluate our own cognitive, emotional, and behavioural processes. In psychology, other terms used for this self-observation include 'reflective awareness', and 'reflective consciousness', which originate from the work of William James.
It highlights what sort of surfaces reflect and what sort of surfaces absorb. Unless given for a specific wavelength (spectral albedo), albedo refers to the entire spectrum of solar radiation. [4] Due to measurement constraints, it is often given for the spectrum in which most solar energy reaches the surface (between 0.3 and 3 μm).
A loop antenna is a radio antenna consisting of a loop or coil of wire, tubing, or other electrical conductor, that for transmitting is usually fed by a balanced power source or for receiving feeds a balanced load. Within this physical description there are two (possibly three) distinct types: Large loop antennas.
The stretch reflex ( myotatic reflex ), or more accurately "muscle stretch reflex", is a muscle contraction in response to stretching a muscle. The function of the reflex is generally thought to be maintaining the muscle at a constant length but the response is often coordinated across multiple muscles and even joints. [1]
Reflector (antenna) Parabolic reflector as part of a Satellite dish. An antenna reflector is a device that reflects electromagnetic waves. Antenna reflectors can exist as a standalone device for redirecting radio frequency (RF) energy, or can be integrated as part of an antenna assembly.
