PROPERTIES OF LIGHT: REAL Flashcards
states that the angle of incidence is equal to the angle of reflection
Law of reflection
This phenomenon occurs when light hits a reflective surface, bouncing back with the same angle of reflection as the angle of incidence.
reflection
when the incident ray of light hits on smooth and shiny finished surfaces such as certain bright metals, mirrors, and even still water; hence, the reflected rays are parallel.
Specular Reflection
happens when the incident ray of light hits rough and irregular surfaces; hence, the reflected rays are not parallel and are scattered all around.
Diffuse Reflection
It is simply the bending of light as it enters from one medium to another.
REFRACTION
.
is discomfort caused by intense, scattered light reflected off rough surfaces, causing visual discomfort and reduced visibility, particularly in reflective environments like wet roads or snowy landscapes.
Glare
occurs on rough, irregular surfaces, creating less defined images.
Diffuse Reflection
refers to the absorbance of light by the object. The object’s optical density can be identified through the object’s index of refraction.
Optical Density
In this phenomenon, light simply passes a slit or a hole and then light as waves are spread out.
DIFFRACTION
In ——, the two light waves meet halfway to create an even brighter or darker kind of light depending on the pattern of crests or trough combinations.
interference
occurs when two light waves meet, resulting in either constructive or destructive interference.
interference
interference can happen in two ways:
constructive and destructive interference
happens when the two crests of waves meet to produce an even taller crest/amplitude.
Constructive Interference
occurs when the crest of one wave meets the trough of another, resulting in cancellation and dimmer light.
Destructive Interference.
