Answer:
[tex]E=2.14\times 10^{-19}\ J[/tex]
Explanation:
We have,
Wavelength of a light is 930 nm
It is required to find the energy of a wave of light. The energy of a wave is given in terms of following as :
[tex]E=\dfrac{hc}{\lambda}\\\\E=\dfrac{6.626\times 10^{-34}\times 3\times 10^8}{930\times 10^{-9}}\\\\E=2.14\times 10^{-19}\ J[/tex]
So, the energy of the wave is [tex]2.14\times 10^{-19}\ J[/tex]
