Science If you want to find the energy quantum of light, you multiply the frequency of the radiation (v) by "h". What is "h"?
weqwewe [10]

Answer:

"h" signifies Planck's constant

Explanation:

In the equation energy E = h X v

The "h" there signifies Planck's constant

Planck's constant is a value, that shows the rate at which the energy of a photon increases/decreases, as the frequency of its electromagnetic wave changes.

It was named after Max Planck who discovered this unique relationship between the energy of a light wave and its frequency.

Planck's constant, "h" is usually expressed in Joules second

Planck's constant = 6.62607015 \times 10^{-34}  J.s

Arlecino [84]
They are dynamic, with winds and waves constantly reworking and moving the barrier island sand.

Changes in sea level also affect these islands.

Most scientists agree that sea level has been gradually rising over the last thousand years, and this rise could be accelerating today due to global warming.

Rising sea level causes existing islands to migrate shoreward.
