What is the energy of a single photon of blue light with a wavelength of 488 nm (488 × 10-9 m)?

Answer : The energy of a photon is,

Explanation :

Formula used :

where,

E = energy = ?

h = Planck's constant =

c = speed of light =

= wavelength =

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

Therefore, the energy of a photon is,

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.
