The ____ a Photon's Wavelength,the ____ Its Energy

Question

The ____ a photon's wavelength,the ____ its energy.  
A) shorter; greater
B) longer; greater
C) shorter; less
D) longer; more variable
E) shorter; more variable

Accepted Answer

According to the equation E=hc/λ, where E is energy, h is Planck's constant, c is the speed of light, and λ is wavelength, we can see that as the wavelength (λ) decreases (shorter), the energy (E) increases (greater). Therefore, option A is the correct choice.
