The de broglie relation λ=h/p can be rewritten in terms of the wave number k as p=kℏ. recall that wave number is defined by k=2π/λ. using the fact that λ=v/f, find the wave numbers k1 and k2 corresponding to frequencies f1 and f2. express your answer as two expressions

What is the conversion factor between kg/m^3 and g/m^3. express your experimental values for the densities in kg/m^3.

The law of the conservation of momentum says that the total momentum of any closed and isolated system cannot
