Lasers have been developed that can generate pulses of light that are only 10 fs (femtoseconds) long. Suppose lamdar =  500nm (Note: 1fs is 1 x 10-15second)

(a) Compute how many wavelengths of light are contained in such a pulse?

(b) If the power during a pulse is 1 mW, find how much energy (ineV) is contained in each pulse?

(c) Compute how many photons are there in each pulse?
