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.

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles
