alternate kanji?

is there such a thing or am i retarded?

見る　and 観る　are both pronounced miru and both mean to watch or look?

分かれ道　pronounced wakaremichi and means splitting path
別れ道　pronounced wakaremichi and means separate path?
not sure about that

also
 陰　and 影　both pronounced kage and both mean shadow？

is this right?

観る is more like "view", like when you're standing at a cliff viewing the ocean.

There are numerous kanjis for 分かれ道, someone else probably knows the difference better than I do.

I'd use 影 as "silouette" instead of shadow, but it depends on context.
