Vedclass · Answer

(A) Given,wavelength $\lambda = 456 \, nm = 456 	imes 10^{-9} \, m$. Speed of light $c = 3 	imes 10^8 \, m/s$. The relationship between frequency $
u$,speed of light $c$,and wavelength $\lambda$ is given by the formula: $c = 
u \lambda$. Rearranging for frequency: $
u = \frac{c}{\lambda}$. Substituting the values: $
u = \frac{3 	imes 10^8 \, m/s}{456 	imes 10^{-9} \, m}$. $
u = 0.0065789 	imes 10^{17} \, s^{-1} = 6.579 	imes 10^{14} \, Hz$. Rounding to two decimal places,we get $
u \approx 6.58 	imes 10^{14} \, Hz$.

Calculate the frequency of visible light whose wavelength is $456 \, nm$.
