Answer : The frequency of the wave is, [tex]4.285\times 10^{14}s^{-1}[/tex]
Solution : Given,
Speed of light = [tex]3.0\times 10^{8}m/s[/tex]
Wavelength of light = [tex]7.0\times 10^{-7}m[/tex]
Formula used :
[tex]\nu=\frac{c}{\lambda}[/tex]
[tex]\nu[/tex] = frequency of light
[tex]\lambda[/tex] = wavelength of light
c = speed of light
Now put all the given values in the above formula, we get the frequency of light.
[tex]\nu=\frac{3\times 10^8m/s}{7\times 10^{-7}m}=4.285\times 10^{14}s^{-1}[/tex]
Therefore, the frequency of the wave is, [tex]4.285\times 10^{14}s^{-1}[/tex]
