umm do yo know this formula for shift in an object's position: $\Large s=t(1-\frac{1}{n})$

3. anonymous

yes but in another shape

4. anonymous

t = real fepth nv > nr u mean i got like that

5. anonymous

and s is raise

6. anonymous

yes, that's right too.

7. anonymous

that will give red that will be the least raise right ?

8. anonymous

yes, absolutely.

9. anonymous

is this equation comes from Raise= real depth - apparent depth ?

10. anonymous

yes it does.

11. anonymous

then i say it and work on it to get the formula u said then i say "thus for the least rise n should be the least refractive index and that is applied on red "" is this a good explanation ?

12. anonymous

yes it is. Good work. :)

thanks
