Opaque:not able to be seen through; not transparent
Reflection:the throwing back by a body or surface of light, heat, or sound without absorbing it.
Transparent:Allowing radiation (most commonly light) to pass through, but causing diffusion. Frosted glass, for example, is translucent to visible light. Compare transparent.
Its Opaque because it cant be seen trough
Its Tranlucent because you could still see the shadow
Its Reflection because u could see the mountains in the water
Each Term Applys to me in my daily life by:
I find Reflection by me looking through a mirror but it comes back and could see myself.
I find Transparent by me sitting down and i look out the window i see the outside so i see through.
I find Translucent by looking at the window curtans and i see a shadow on the other side.
