Acertain type of laser emits light that has a frequency of 7.2 × 1014 hz. the light, however, occurs as a series of short pulses, each lasting for a time of 3.7 × 10-11 s. (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 108 m/s. how many wavelengths are there now in one pulse?
