Answer:
Explanation:
Given
Wavelength of radiation [tex]\lambda =784\ m[/tex]
We know Energy of wave with wavelength [tex]\lambda[/tex] is given by
[tex]E=\frac{hc}{\lambda }[/tex]
where h=Planck's constant
c=velocity of light
[tex]\lambda [/tex]=wavelength of wave
[tex]E=\frac{6.626\times 10^{-34}\times 3\times 10^8}{784}[/tex]
[tex]E=2.53\times 10^{-28}\ J[/tex]
Hence the energy of the wave with wavelength 784 m is [tex]2.53\times 10^{-28}\ J[/tex]
