what is light
refraction
change of direction fo a ray of light
medium
a medium is an objects that transfers light from one object to another
normal
a normal is the exact point of incidence where the light hits
lights transmission
light transmission is where passes through an object
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
reflection
mirrors
a mirror is a reflective object that reflects light
angle of incidence
a point of incidence is the exact angle of where a ray of light hit of a mirror
virtual images
virtual images are rays of light that spead after hitting off a mirror or refective object
specular reflection
where a beam of light hits a flat surface
real image
a real image is where light rays hit off a mirror
then all comes together
diffuse reflection
diffuse relection is where light hits off a very rough surface making different angles of reflection.
lumonois objects
luminous objects are objects that make light
fireflies
stars
candle
light bulb
sun
absobtion of light
metal
water
colourd objects
darker colours
electromagnetic spectrum
gamma
x rays
ultra violet
visable light
infared
microwaves
non lominous objects
non luminous objects do not make there own light
trees
moon
metals
rocks
