Planck's Constant Is About 7 × 10^{- 34}, in Metric

Planck's constant is about 7 × 10^{- 34}, in metric units. Suppose that Planck's constant were larger than it is actually is. Which of the following would then occur?

A) Individual photons would have shorter wavelengths, making it harder to observe individual photons.
B) Individual photons would have larger energies, making it easier to observe individual photons.
C) Individual photons would have larger wavelengths, making it easier to observe individual photons.
D) Individual photons would move faster, even though the overall wave speed of electromagnetic radiation would not change.
E) Individual photons would have smaller energies, making it harder to observe individual photons.
