Answer:
Frequency, [tex]f=6.67\times 10^{14}\ Hz[/tex]
Explanation:
Wavelength of a light wave is 450 nm. It is required to find the frequency of this light wave. The speed of light is given by c. So,
[tex]c=f\lambda[/tex]
f is the frequency of this light
[tex]f=\dfrac{c}{\lambda}\\\\f=\dfrac{3\times 10^8}{450\times 10^{-9}}\\\\f=6.67\times 10^{14}\ Hz[/tex]
So, the frequency of this light is [tex]6.67\times 10^{14}\ Hz[/tex].
