A certain type of laser emits light that has a frequency of 5.7 1014 Hz. The light, however, occurs as a series of short pulses, each lasting for a time of 2.5 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 2.3 108 m/s. How many wavelengths are there now in one pulse?
