A uniform stationary ladder of length L and mass M leans against a smooth vertical wall, while its bottom legs rest on a rough horizontal floor. The coefficient of static friction between floor and ladder is μ.

A light wave is traveling straight up out of the ocean then moves out into the air how do you expect the movement of the light wave to change the light wave will

To verify that this expression for (vf) α has the correct units of velocity, you need to perform some unit analysis. begin by finding the equivalent of a volt in terms of basic si units.
