Question

The energy of a photon is give as Then the wavelength  of a photon is.

Solution

Correct option is

6.56nm

         fraction numerator 6.63 cross times 10 to the power of minus 34 end exponent cross times 3 cross times 10 to the power of 8 over denominator 3.03 cross times 10 to the power of minus 19 end exponent end fraction space space space space lambda equals 6.56 n m
