Lens in eye of an octopus focuses light onto retina.
Power of the lens is 118D
a) Show focal length is 8.5mm
Distance from lens to retina is 2cm
b) Calculate shortest distance from the eye at which an object
may be focused
The lens is in contact with seawater
c) Calculate what would happen to this shortest
distance
d) Calculate speed of light in seawater, refractive index =
1.37
