What are two equations for the energy of light? Identify each variable.

E = hv

E = hf

Explanation:

there are basically two equations for energy in light.

E = hf

where E is the energy of the photons. the unit is joules

h = the planck's constant . the unit is joules second

f = frequency of light. the unit is Hertz

E = hv

E is the energy of a particlar quantum under study.

h = planck,s constant which is usually 6.62607555 × 10^-34 js^-1

v = the frequency of the light.

if you already have the answer to (a), then just work out how many periods there are in 1 minute, and that's the answer to (c).

s the environmental science is a broader field that incorporates many elements of earth and life sciences, whereas ecology is usually more focused on how organisms interact with each other and their surroundings, and often on a very specific population of living things. soo yea
