B is the correct answer
y=Asin(wt-kx)
A=amplitude
f=frequency
x=wavelength
since refraction is not on the wave formula,then option B is the correct answer
        
                    
             
        
        
        
 The second diver have to leap to make a competitive splash by 4.08 m high.
<h3>What is potential energy?</h3>
The energy by virtue of its position is called the potential energy.
PE = mgh
where, g = 9.81 m/s²
Given is the diver jumps from a 3.00-m platform. one diver has a mass of 136 kg and simply steps off the platform. another diver has a mass of 100 kg and leaps upward from the platform. 
The potential energy of the first diver must be equal to the second diver.
P.E₁ = P.E₂
m₁gh₁ = m₂gh₂
Substitute the vales, we have
 136 x 3  = 100 x h₂
h₂ = ₂4.08 m 
Thus, the second diver need to leap by 4.08 m high.

Density is defined as (mass) per unit (volume).  So in order to calculate 
the density of a glob of some substance, you pretty much have to measure 
its mass and its volume.
