34.3 Exercise 1

The characteristic length of entities in Superstring theory is approximately $\text{10}^{- \text{35}} \text{m}$ .

(a) Find the energy in GeV of a photon of this wavelength.

(b) Compare this with the average particle energy of $\text{10}^{\text{19}} \text{GeV}$ needed for unification of forces.
