Light
Light travels in straight lines and if theres an opaque object a the light hits it
it would make a object e.g
if the light source gets closer to object it will make a smaller shadow
light travels in straight lines
do all things reflect light?
no for example in the cloakroom i can see the red coat easierthan the black coat because the red one is shining more in my eyes
if the light object is opaque the shadow is darker if its translution the shadow is light and if its transparent
theres no shadow
