Vedclass · Answer

(B) The relationship between frequency $(v)$,speed of light $(c)$,and wavelength $(\lambda)$ is given by the formula: $v = \frac{c}{\lambda}$.Given: $c = 3 	imes 10^8 \ m \ s^{-1}$ and $\lambda = 750 \ nm = 750 	imes 10^{-9} \ m$.Substituting the values: $v = \frac{3 	imes 10^8 \ m \ s^{-1}}{750 	imes 10^{-9} \ m} = \frac{3}{750} 	imes 10^{17} \ Hz = 0.004 	imes 10^{17} \ Hz = 4 	imes 10^{14} \ Hz$.

Calculate the frequency if the wavelength is $750 \ nm$.
