The product of (wavelength) times (frequency) is always the same number ...
the speed of the wave in whatever material it's traveling through. So if the
frequency is increased, then the wavelength must <em><u>de</u></em>crease by the same
factor, in order to keep the product the same.
The answer would be 981 newtons or 220.46 pounds.
The green wavelengths are reflected, causing green to be the only color we see in certain parts of plants.
Best of luck, my man.
