Question

a bird is flying 12m above the surface of pond. what is appearant position of bird as viewed by fish 1m below the surface

Answer 1

let surface of pond be the coordinate system

since bird is above surface

Ybird=+12m

and fish is below

Yfish=-1m

Ybird/fish=Ybird-Yfish

=12-(-1)

=13m

hope this helps
