Three difference between wavelength and frequency ?

Hi,
Wavelength: 
1.Wavelength measures the distance from one point of a wave to the same point on an adjacent wave.
2.Wavelengths are measured in nanometres.
3.The wavelength of the wave is inversely proportional to the energy of the wave.
Frequency:
1.Frequency represents how many waves are produced from the source per second.
2.Frequencies are measured in hertz or waves per second.
3.The frequency is linearly proportional to the energy of the wave.
Hope this Helps you.

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j
