Why is it easier to see fine print in brighter light than in dimmer light?
a. This is not so, it is easier to see fine print in dimmer light than in brighter light.
b. Because the refractive power of the eye increases as the light intensity increases.
c. In brighter light, the f-number of the eye increases.
d. In brighter light, the longer wavelengths dominate.

If 33 atom % Cu is mixed into a Ni crystal at a temperature of 473 K (200°C), determine the change in the GFE relative to segregated Cu and Ni for 1 mole of total atoms if the enthalpy of solution for Cu into Ni is 0.11 eV/atom, according to data in Hultgren et al.
(a) What is the GFE change for the mixing? (b) Based upon your result, should it be possible to mix 33 atom % Cu into Ni at 473 K? Explain your answer and compare this result to the phase diagram in Figure 5.7.
