The strength of a rectangular beam varies jointly as its width and the square of its depth. if the strength of a beam 12 inches wide by 22 inches deep is 3400 pounds per square inch, what is the strength of a beam 9 inches wide and 18 inches deep?

What is the relationship between the wavelength of a wave and it's energy?
