Light travels at 3. 0 × 108 m/s in a vacuum and slows to 2. 0 × 108 m/s in glass. What is the index of refraction of glass?.

Sergio039 [100]

The required value of the index of refraction of glass is 1.5.

Given data:

The speed of light in a vacuum is, $c = 3.0 \times 10^{8} \;\rm m/s$ .

The speed of light in a glass is, $v = 2.0 \times 10^{8} \;\rm m/s$ .

Light has the tendency to travel from one medium to another, then the difference between the speeds of light in various mediums is determined by a term, known as the index of refraction. The mathematical expression for the index of refraction of glass is,

n = c / v

Solving as

$n = \dfrac{3.0 \times 10^{8}}{2.0 \times 10^{8}}\\\\n = 1.5$

Thus, we can conclude that the required value of the index of refraction of glass is 1.5.

Monochromatic light from a distant source is incident on a slit 0.705 mm wide. On a screen 2.13 m away, the distance from the ce

vampirchik [111]

Answer:

492.183 nm

Explanation:

x = Distance from the central maximum to the first minimum = 1.35 mm

l = Distance of screen = 2.13 m

d = Distance of gap = 0.705 mm

m = Order = 1

We have the relation

$tan\theta=\dfrac{x}{l}\\\Rightarrow \theta=tan^{-1}\dfrac{1.35\times 10^{-3}}{2.13}\\\Rightarrow \theta=0.04^{\circ}$

$dsin\theta=m\lambda\\\Rightarrow \lambda=\dfrac{dsin\theta}{m}\\\Rightarrow \lambda=\dfrac{0.705\times 10^{-3}\times sin0.04}{1}\\\Rightarrow \lambda=4.92183\times 10^{-7}=492.183\ nm$

The wavelength of the light is 492.185 nm
