# In the 1980s, the term picowave was used to describe food irradiation in order to overcome public resistance by playing on the wellâ€”known safety of microwave radiation. Find the energy in MeV of a photon having a wavelength of a picometer.

To determine

The photon energy in MeV having a wavelength of a picometer

Explanation

Given info:

The wavelength is given

â€ƒâ€ƒÎ»=1.00â€‰pmÎ»=1.00Ã—10âˆ’12m

Formula used:

The energy can be calculated as

â€ƒâ€ƒE=hcÎ»

Calculation:

Substituting the values, we get

â€ƒâ€ƒE=6.63Ã—10âˆ’34â€‰J/sÃ—3Ã—108â€‰m/s1
