Sagot :
Answer:
[tex]f=4.47\times 10^{14}\ Hz[/tex]
Explanation:
Given that,
The wavelength of light, [tex]\lambda=670\ nm=670\times 10^{-9}\ m[/tex]
We need to find the frequency of the light. The relation between the frequency and wavelength is given by :
[tex]v=f\lambda[/tex]
The speed of light is equal to c.
So,
[tex]f=\dfrac{c}{\lambda}\\\\f=\dfrac{3\times 10^8}{670\times 10^{-9}}\\\\f=4.47\times 10^{14}\ Hz[/tex]
So, the frequency of light is equal to [tex]4.47\times 10^{14}\ Hz[/tex].
