According to equation m=m0/sqrt (1-(v2-c2)), object will gain mass on increasing velocity but in case of light why it's mass is not increasing and if light has 0 mass then how it can show particle nature as if photon is a particle of mass=0 then how can it even exist ?
Answers
Explanation:
A velocity-addition formula is an equation that relates the velocities of moving objects in different reference frames.

When two objects are moving slowly compared to speed of light, it is accurate enough to use the vector sum of velocities:
s
=
u
+
v
.
As the velocity increases towards the speed of light, the vector sum of velocities is replaced with:
s
=
v
+
u
1
+
vu
/
c
2
.
Composition law for velocities gave the first test of the kinematics of the special theory of relativity when, using a Michelson interferometer, Hyppolite Fizeau measured the speed of light in a fluid moving parallel to the light.
