Lithium has the highest specific heat of any pure metal. The temperature of a 25.00g sample of lithium will increase by 7.69°C when 684.4 J of energy is added to it. What is lithium's specific heat in the unit?

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
