However light actually slows down as it passes through different media. You use this equation to solve for frequency to plug into the first equation. The wave equation is.
Using the common physics formula distance equals rate times time or d r x t you can calculate how long a.
Because distances across the. Using the common physics formula distance equals rate times time or d r x t you can calculate how long a. Write the formula for distance. For instance when it moves through glass it slows down to about two-thirds of its speed in a vacuum.
