    1. ______________ Calculate the slope of trend line. The slope is the experimental index of refraction for water.
    2. ______________ __________ Use the trend line to calculate the actual depth for a coral head the image of which appears to be 100 cm underwater.
    3. ______________ __________ Use the trend line to calculate the image depth for a coral head that is actually 200 cm underwater.
    4. ______________ Ocean water in the western Pacific is reported to have an an actual index of refraction of 1.34. What is the percentage error?

period τ = 1 ÷ (frequency f )
velocity ѵ = wavelength λ * frequency f
percent error= (experimental value−expected value) (expected value)
