Light enters from air into diamond which has refractive index of 2.42 calculate the speed of light in diamond the speed of light

ELEN [110]

The speed of light in diamond is $1.24\cdot 10^8 m/s$

Explanation:

The index of refraction of a material is equal to the ratio between the speed of light in vacuum and the speed of light in the material:

$n=\frac{c}{v}$

where

n is the index of refraction

c is the speed of light in vacuum

v is the speed of light in the material

In this problem, we have:

n = 2.42 is the refractive index of diamond

$c=3.0\cdot 10^8 m/s$ is the speed of light in vacuum

Solving for v, we find the speed of light in diamond:

$v=\frac{c}{n}=\frac{3\cdot 10^8}{2.42}=1.24\cdot 10^8 m/s$

A force =(16.8N/s)t is applied to an object of m=45.0kg. Ignoring friction, how far does the object travel from rest in 5.00s?

kirza4 [7]

Answer:

Explanation:

a = F/m = 16.8t/45 = 0.373*t

v = ∫a*dt = ∫(0.373*t)dt = 0.1865*t²

x = ∫v*dt = 0.1865∫(t²)dt = 0.062*t³

For t = 5.0 sec,

x = 0.062*(5)^3 = 7.75 m
