which choice solves the equation c = λ·f for frequency at the speed of light? c = speed of light λ =…

Explanation:

Step1: Isolate the frequency variable

Given $c = \lambda\cdot f$, we want to solve for $f$. Divide both sides of the equation by $\lambda$. $\frac{c}{\lambda}=\frac{\lambda\cdot f}{\lambda}$

Step2: Simplify the right - hand side

Since $\frac{\lambda\cdot f}{\lambda}=f$, we get $f=\frac{c}{\lambda}$.

Answer:

The correct choice is $f = \frac{c}{\lambda}$
