What wavelength of radiation has photons of energy 2.87×x10−18 j?
Masja [62]
The energy of a photon is given by
E=hf
where h is the Planck constant and f is the frequency of the light. 
Given the relationship between the frequency f, the wavelength \lambda and the speed of light c for an electromagnetic wave:
f= \frac{c}{\lambda}
we can rewrite the energy of the photon as
\lambda =  \frac{hc}{E}
and by substituting h=6.6 \cdot 10^{-34 J}, c=3 \cdot 10^8 m/s and E=2.87 \cdot 10^{-18}J, we get the wavelength of the photon:
\lambda =  \frac{hc}{E}=6.9 \cdot 10^{-8} m = 69 nm
