# Speed Of Light and stimilation

Spin_Network
On a par with Einsteins "riding-along-on-a-lightbeam", if I was travelling at the front of a beam of light, and I shone a Laser in the direction of travel, will the Laserbeam work?

Do Laser's travel well?

i think it would work perfectly well and if u could measure the speed of laser beam it would be travelling at c of course.

$$\frac{v+c}{1+\frac{vc}{c^2}}=\frac{v+c}{1+\frac{v}{c}}=$$
$$c\frac{v+c}{v+c}= c$$.
