Answer:
[tex]6.17\cdot 10^{14} Hz[/tex]
Explanation:
The relationship between frequency and wavelength for any electromagnetic wave is:
[tex]c=f \lambda[/tex]
where
[tex]c=3\cdot 10^8 m/s[/tex] is the speed of light
f is the frequency
[tex]\lambda[/tex] is the wavelength
In this problem, we have green light with wavelength
[tex]\lambda=486.1 nm=486.1 \cdot 10^{-9} m[/tex]
Therefore, re-arranging the previous equation and plugging the numbers in, we can find the frequency of the emitted light:
[tex]f=\frac{c}{\lambda}=\frac{3\cdot 10^8 m/s}{486.1 \cdot 10^{-9}m}=6.17\cdot 10^{14} Hz[/tex]
