Question

Light is one of the slowest travelling energy with a speed of 3 × 10–8 ms-1

Answer 1

no you are wrong at this point light is the fastest travelling energy with a speed of 3 into 10 to the power 8 metre per second

Answer 2

given statement is false, light is the fastest travelling energy with speed of 3 × 10^8 m/s.

most important properties of light are ;

• Nothing can travel faster than the speed of light in vaccum.
• light in a vaccum always travels at the same speed.

as you know , kinetic energy ∝ (speed)²

if light is the fastest particle it means kinetic energy of light will be largest. it means, light is the fastest travelling energy with speed 3 × 10^8 m/s .
