A red laser emits photons by a wavelength of 635 nm.

1. If this laser has a power of 23 W, how many photons does it emit in 1 s?

2. If the light emitted by the laser is absorbed with a black sail, what is the force on the sail?

3. If the light from this laser is reflected from a mirror, what is the force on the mirror?
