luminous objects are objects that make light
reflection
diffuse reflection
diffuse relection is where light hits off a very rough surface making different angles of reflection.
real image
a real image is where light rays hit off a mirror
then all comes together
specular reflection
where a beam of light hits a flat surface
virtual images
virtual images are rays of light that spead after hitting off a mirror or refective object
angle of incidence
a point of incidence is the exact angle of where a ray of light hit of a mirror
mirrors
a mirror is a reflective object that reflects light
lights transmission
sun rays going through water or class
this is a good example because the sun is cery bright and has alot of light rays and the water and glass is very translucent/transparent
light transmission is where passes through an object
refraction
normal
a normal is the exact point of incidence where the light hits
medium
a medium is an objects that transfers light from one object to another
change of direction fo a ray of light
