▪ [tex]\tt{6.1 \times 10 {}^{ - 9}} [/tex]
Remember the speed of light is [tex]\rm{\small 299,792,458} [/tex]
Recall the frequency of a wave is [tex]\rm{\small f = \dfrac{ v}{\lambda} .}[/tex]
[tex]\begin{gathered}\begin{aligned} & \bold{} \\ & \quad {\begin{array}{l} \rm{ \large f = \dfrac{299792458 \frac{m}{s} }{6.1* {10}^{ - 9}m } \rightarrow f = 4.914630459...*10 {}^{16} Hz } \end{array}}\end{aligned}\end{gathered}[/tex]
[tex]\begin{gathered}\begin{aligned} & \bold{} \\ & \quad {\begin{array}{l} \rm{ \large \implies f \approx \rm{4.9* {10}^{16}Hz }} \end{array}}\end{aligned}\end{gathered}[/tex]
