Vedclass · Answer

(B) The relationship between frequency $(
u)$,speed of light $(c)$,and wavelength $(\lambda)$ is given by the formula: $
u = \frac{c}{\lambda}$.Given:$c = 3 	imes 10^8 \ ms^{-1}$$\lambda = 600 \ nm = 600 	imes 10^{-9} \ m = 6 	imes 10^{-7} \ m$.Substituting the values into the formula:$
u = \frac{3 	imes 10^8 \ ms^{-1}}{6 	imes 10^{-7} \ m} = 0.5 	imes 10^{15} \ Hz = 5.0 	imes 10^{14} \ Hz$.Therefore,the correct option is $B$.

Calculate the frequency in $Hz$ of orange colour light having wavelength $600 \ nm$. $[c = 3 \times 10^8 \ ms^{-1}]$
