The fact that cm is asked for in the problem allows us to use the cm/s value for the speed of light:
Light travels at a speed of 1.86 x 10 5 miles per second. The frequency, f, of a wave is the number of times a wave's crests pass a point in a second.if you watch a water wave in the bath pass over one of your toes twice every second the frequency of the wave is 2 hz. You must show all the work outlined in the steps in the example problems. What is the period of the waves? And v is the velocity of the object in m/sec. speed of a compression wave in a fluid. 5 steps to a 5 practice problems forces.
