Question

What is the dimension of speed of light

Answer 1

Answer:

Explanation:

[ LT^-1]

Answer 2

Whatever there's given speed of light, speed of sound, speed of any vehicle and speed of any others,... all are one thing - "speed"!!!

So all kinds of speed do have same dimension, don't they?

Now, what's the formula of speed?

Speed = Distance / Time, we know.

Since distance is a form of length, its dimension is [L], or simply L.

And we know the dimension of time, [T], or simply T.

Now,

[Speed] = [Distance] / [Time]

[Speed] = L / T

Now we got L / T. In exponential form, we write the whole as LT^(-1).

Or we write including the dimension of mass M as,

M^0 · L^1 · T^(-1)
