What is the energy of a photon (in units of h) that has a wavelength of 300 nm?
(c = 3.00 x 108 m/s)

1 x 10^17 h
1 x 10^15 h
1 x 10^6 h
1 x 10^-2 h

Explanation:

Considering:-

Where,  

h is Planck's constant having value

c is the speed of light having value

is the wavelength of the light

Given, Wavelength = 300 nm

Also, 1 m = nm

So,  

Wavelength = m

Applying in the equation as:-

convalent bond :

is a chemical bond formed by the sharing of electron between 2 atoms.

it is the direct chemical bond between 2 atoms.

in bond formation atoms are involved here.

electrovalent bond:

is a chemical bond defined as electroststic attraction between 2 atoms.

it is the electrostatic attraction between 2 atoms.

in bond formation, ions are involved here.

hope it

and ur welcm
