If the speed of light in a substance is 2.26 x 10^8 m/s, what is the index of refraction of that substance?
vladimir1956 [14]

Answer:

1.33

Explanation:

speed of light in vacuum, c = 3 x 10^8 m/s

speed of light in medium, v = 2.26 x 10^8 m/s

The refractive index of the medium is given by

μ = speed of light in vacuum / speed of light in medium

μ = (3 x 10^8) / (2.26 x 10^8)

μ = 1.33

The 630-nm light from a helium-neon laser irradiates a grating. The light then falls on a screen where the first bright spot is
dimaraw [331]

Answer:

464.8 nm

Explanation:

The second wavelength of light can be calculated using the next equation:

\lambda = \frac{x*d}{L}        

<u>Where:</u>

<em>λ : is the wavelength of light</em>

<em>x: is the distance from the central maximum</em>

<em>d: is the distance between the spots                      </em>

<em>L: is the lenght from the screen to the bright spot</em>

For the first wavelength of light we have:

\lambda_{1} = \frac{x_{1}*d}{L}

630 \cdot 10^{-9} m = \frac{0.61 m*d}{L}

\frac{d}{L} = \frac{630 \cdot 10^{-9} m}{0.61 m} = 1.033 \cdot 10^{-6}  (1)    

For the second wavelength of light we have:

\lambda_{2} = \frac{x_{2}*d}{L}

\lambda_{2} = 0.45 m*\frac{d}{L}   (2)  

By entering equation (1) into equation (2) we have:

\lambda_{2} = 0.45 m* 1.033 \cdot 10^{-6} = 4.648 \cdot 10^{-7} m = 464.8 nm

Therefore, the second wavelength is 464.8 nm

I hope it helps you!

A runner goes around a 1 mile track if they end up at their starting position what is their dosplacement
mario62 [17]

Answer:

The displacement is zero

Explanation:

Displacement is a vector that connects the starting position of motion of an object to the final position. It is a vector quantity, so it has both magnitude and direction.

Viceversa, distance is a scalar quantity that measures the total length of the path covered by the object during its motion.

In this problem, we are interested in the displacement.

We are told that the runner goes around a 1 mile track, and he ends at his starting position: this means that his final position is equal to the starting position, therefore the displacement is zero.

Prove 1/P = 1/P1 + 1/P2
Sati [7]

Answer:

Proof:

|----------(R1)-------------(R2)---------|

Let the resistances be R1 , R2 connected in series. And the potential difference be V ;

We know that :

P1 = V²/R1 ..........(1) and

P2 = V²/R2 ...........(2)

In series combination , the net resistance is the algebraic addition of individual resistance :

R = R1 + R2

=> V²/P = V²/P1 + V²/P2

=> 1/P = 1/P1 + 1/P2

Explanation:

Copied it from a different brainly question that is this question. Please try to find it on brainly instead of asking it'd make it much easier.
