Which describes a relationship when calculating the energy of a photon?

the energy of the photon is directly proportional to frequency.
the energy of the photon is inversely proportional to frequency.
as the energy of the photon increases, planck’s constant increases.
as the energy of the photon increases, planck’s constant decreases.

Correct A). The energy of the photon is directly proportional to frequency.  

A photon is a quantum of electromagnetic radiation, and quantum is the smallest unit of quantity. Thus the photon is the smallest unit of light. The energy is directly proportional to the frequency of the photon and inversely proportional to wavelength.

It means higher the frequency of photon greater will be its energy and lesser will be its wavelength.

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).
