A certain type of laser emits light that has a frequency of 7.4x 1014 Hz. The light, however, occurs as a series ofshort pulses, each lasting for a time of 4.4 x 10^-11 s.(a) How many wavelengths are there in one pulse? (b) The lightenters a pool of water. The frequency of the light remains thesame, but the speed of the light slows down to 2.3 x 10⁸m/s. How many wavelengths are there now in one pulse?
