A certain type of laser emits light that has a frequency of 5.4 = 1014 Hz. The light, however, occurs as a series of short pulses, each lasting for a time of 3.0 x 107115, (a) How many wavelengths are there in one pulse? (b) The light enters a pool of water. The frequency of the light remains the same, but the speed of the light slows down to 2.3 x 10 m/s. How many wavelengths are there now in one pulse? o=t B s [ - (b)N = Number | 16201 | Units | This answer has no units <
