18 m
use Z = d2/ ?
589 nm, 3??108?m/s
v=wavelength*f (v is velocity)
f remains constant for refracted ray
refractive index water/refractive index air=1.33/1=wavelength of incident/wavelength of refracted ray
1.33=589/wavelength
wavelength=589/1.33=442.85nm
frequency=v/wavelength=3*10^8/589*10
=5.0933*(10^15)Hz
note f remains constant so you can use eqn for refracted ray by finding vel of refracted ray
444 nm, 2.26?108?m/s
