Having become stranded in a remote wilderness area, you mustlive off the land while you wait for rescue. One morning, youattempt to spear a fish for breakfast.
You spot a fish in a shallow river. Your first instinct is toaim the spear where you see the image of the fish, at anangle 𝜙=43.40∘ϕ=43.40∘ with respect to the vertical, asshown in the figure. However, you know from physics class that youshould not throw the spear at the image of the fish, because theactual location of the fish is farther down than it appears, at adepth of 𝐻=0.9000 m.H=0.9000 m. This means youmust decrease the angle at which you throw the spear. This slightdecrease in the angle is represented as 𝛼α inthe figure.
If you throw the spear from aheight ℎ=1.200 mh=1.200 m above the water,calculate the angle decrease 𝛼α . Assume that the indexof refraction is 1.0001.000 for airand 1.3301.330 for water.
