Answer:
1. directly
2. inversely
Explanation:
The relationship between the energy of a photon and its frequency is dictated by another simple equation:
E = hv = hc/λ
where E is the energy in kiloJoules per mole, h is Planck's constant with a value of 6.626 x 10-34 Joule-seconds per particle, λ is the wavelength of light λ in meters, and c is the speed of light with a constant value of 300 million meters per second. From this equation, it is clear that the energy of a photon is directly proportional to its frequency and inversely proportional to its wavelength. Thus as frequency increases (with a corresponding decrease in wavelength), the photon energy increases and vice versa.
