yes but in another shape

Answer 4

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

Answer 5

and s is raise

Answer 6

yes, that's right too.

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

Answer 8

yes, absolutely.

Answer 9

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

Answer 10

yes it does.

Answer 11

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 ?

Answer 12

yes it is. Good work. :)
