The frequency of a photon that has an energy of 3.7 × 10-18 j is s-1.

The frequency of the photon is

Explanation:

The relationship between energy and frequency is given by Planck's equation, which is:

where,

h = Planck's constant =

E = energy of the photon =

= frequency of photon = ?

Putting values in above equation, we get:

Hence, the frequency of the photon is

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.
