Find the wavelength (in nm) of a 2.52 eV photon. a. 492.34127 nm. b. 585.88611 nm. c. 541.5754 nm. d. 418.49008 nm.

The correct option is (a).

Explanation:

Given that,

The energy of photon, E = 2.52 eV

We need to find the wavelength of the photon in nm. The formula for the energy of a photon is given by :

The nearest option is a) i.e. 492.34127 nm.

a) cold, dry

explanation:

continental polar masses are cold and dry air masses because the cold air cannot hold much moisture. as they move into warmer air, they can trigger precipitation.

second mirror gathers light from a faraway object and reflects it to another mirror. - a.
