Answer:
In absence of water :- angle = arcLength/radialDistance = 20×10-2 / 4 = 5×10-2 rad
in prdesence of water ;-
apparant depth of fish below water = 2/(4/3) = 1.5m ; hence, radial distance = 2+1.5= 3.5 m ;
angle = arcLength/radialDistance = 20×10-2 / 3.5 = (40/7)×10-2 rad
ratio = [ (40/7)×10-2 ] / [ 5×10-2 ] = 8/7
