During laser vision correction, a brief burst of 193 nm ultraviolet light is projected onto the cornea of the patient. it makes a spot 1.10 mm in diameter and deposits 0.450 mj of energy. calculate the depth (in μm) of the layer ablated, assuming the corneal tissue has the same properties as water and is initially at 34.0°c. the tissue's temperature is increased to 100°c and evaporated without further temperature increase. (the heat capacity of water is 4,186 j/(kg. °c), its latent heat of vaporization is 2,256 kj/kg, and its density is 1,000 kg/m^3.)
