Solve the all parts of given question:

Question: A ruby laser emits an intense pulse of light that lasts a mere 30.0ns. The light has a wavelength of 690 nm, and each pulse has energy of 700mJ.

Part I: How many photons are emitted in each pulse?

Part II: What is the rate of photon emission, in photons per second, during the 30.0ns that the laser is "on"?

I want help to find how many photons are emitted in each pulse.
