Assume light is traveling through an optical medium of n1 and is incident on a boundary with a different optical medium with n2.

If the speed of light in the second medium is half the value compared to that of the first one, then one properly concludes that

That n2 = 2*n1.  That is, the index of refraction is twice as big in medium 2 since v=c/n

Why do we measure volume
Misha Larkins [42]

Explanation:

Volume is often quantified numerically using the SI derived unit, the cubic metre. The volume of a container is generally understood to be the capacity of the container; i. e., the amount of fluid (gas or liquid) that the container could hold, rather than the amount of space the container itself displaces.

We don't use units like triangular prism feet or spherical kilometers because the three axes don't make a "corner" of any other shape other than a cube.

Glad I was able to help!!

A box is given a push so that it slides across the floor. How far will it go, given that the coefficient of kinetic friction is
IRINA_888 [86]

Answer:

s=4.44 m

Explanation:

Given that

Coefficient of the kinetic friction ,μ = 0.13

Initial velocity ,u= 3.4 m/s

Final velocity of the box ,v= 0 m/s

The acceleration due to friction force

a= - μ g

Now by putting the values in the above equation

a= - 0.13 x 10    ( take g= 10 m/s²)

 a= - 1.3 m/s²

We know that

v²= u ² + 2 a s

s=distance

a=acceleration

v=final speed

u=initial speed

Now by putting the values in the above equation

0²= 3.4² - 2 x 1.3 x s

s=\dfrac{3.4^2}{2\times 1.3}\ m

s=4.44 m

The distance cover by box will be 4.44 m.
