And what we end up with for the energy then is 2.84 times 10 to the -19 joules.
我们算出的能量是,2,84乘以10的-19次方焦耳。
And then we have c, the speed of light, 2.998 times 10 to the 8 meters per second.
然后我们知道光速等于,2,998乘以10的8次方米每秒。
This thing does 2 gig worth of operations.
G就是10的9次方。
So for every photon we have 2.84 times 10 to the -19 joules.
每一个光子有,2,84乘以10的-19次方焦耳。
So what we end up with for the number of photons in this laser beam of light is 2.1 times 10 to the 17 photons.
这个激光束的数目是,2,1乘以10的17次方。
