The top picture should be obvious. The rope is tied at one end. The person holding it provides energy in the form of vibrations moving up and down the way the diagram is shown. The wave can also be created by the rope moving sideways.
The bottom picture is much harder. T energy is provided by the forefinger. It has to move. If you just stick your finger in the water, all that will happen is that you will move some water (very little in the scheme of things.
So the energy is provided by a moving forefinger.
We have that the letter A in the diagram below given as

Generally, the amplitude of a wave is the maximum displacement of the wave in the medium from its initial position.
Amplitude is denoted with the letter A
Therefore,Amplitude

Answer : 
Explanation :
The word kinematics means the study of motion. Kinematic variables gives the description of the motion of the body.
Displacement, Velocity, acceleration and time are associated with the motion of particle.
Wavenumber is defined as the frequency of wave, which is measured in cycles per unit distance.
Wave number is also defines as:
where, 
is wavelength
since, 
So, 
Where, 
is angular frequency and 
is velocity of wave.
Hence, the relationship between the angular wavenumber k and and kinamatic variable V is
Wavelength = 600 nm = 600 × 10^(-9)
speed of light = c = 3 × 10^8
planck constant = h = 6.63 × 10^(-34)
energy of photon = hc/wavelength
= 6.63 × 10^(-34) × 3 × 10^8/600 × 10^(-9)
= 1.9 × 10^(-25)/6 × 10^(-7)
= 0.31 × 10^(-16)
= 3.1 × 10^(-17)
