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
