A student was tuned into 99.5 fm on the radio dial. They found the length of half of the wavelength to be 1.48 meter. Determine what is the measured velocity?
The wavelength of green light is 550 nanometers. Determine what is its frequency? (c = 3.00 x 108 m/s)
Find which equation can't be used to calculate the speed of light in vacuum?
