What are the rules to significant figures and what are the conversions in SI? What happens to waves when you go from a dense to less dense and a less dense to more dense medium with one pulse sent?

The captain of a crab boat on the coast of Alaska notes that in a time period of t = 8 minutes, the boat goes up and down n= 26 times. Input an expression for the frequency of the ocean wave, f. What is the frequency, in hertz?  If the crests are d = 100.0 m apart how fast are the waves traveling in meters per second?

Consider the surface density wave 01 = 010e (w+30-ar³/4) where t is time, the azimuthal angle, which increases clockwise, and r the radial coordi- nate. w is the angular frequency (w > 0), a is a positive constant. 10 is the amplitude of the wave. 01 1. Using mathematical arguments show whether the pattern described by σ₁ is rotating clockwise or anticlockwise. 2. Using mathematical arguments show whether the pattern described by σ is a trailing or a leading spiral.
