Hospital X-ray generators emit X-rays with wavelength of about 15.0 nanometers (nmnm), where 1nm=10−9m1nm=10−9m. What is the energy of a photon of the X-rays

Answer :  The energy of a photon of X-rays is

Explanation : Given,

Wavelength of photon =

conversion used :

Formula used :

As,

So,

where,

= frequency of photon

h = Planck's constant =

= wavelength of photon  =

c = speed of light =

Now put all the given values in the above formula, we get:

Therefore, the energy of a photon of X-rays is

c.

explanation:

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
