The Earth casts a shadow. Why does this shadow taper?
Venus also casts a shadow. On Earth we just see a small spot when Venus transits the Sun.
Because the Sun is not a point source of light but an extended object. Does that answer your question or have I misunderstood what taper means here?
You mean if it were a point source, the shadow would not tapper (thinned) . So would it get thicker?
Thanks. I got it
