A spotlight on a boat is y = 2.6 m above the water, and the light strikes the water at a point that is x = 8.6 m horizontally displaced from the spotlight. The depth of the water is 4.0 m. Determine the distance d, which locates the point where the light strikes the bottom.


m

  • Physics - ,

    Find the angle of incidence (arctan8.6/2.6)

    then use snells law to find the angle of refraction.

    I am not certain if d is the distance from the boat...assuming so...

    d= 8.6+4ctn(anglerefraction)

    checkthat.
