Serhud [2]

Answer:

\theta=15.70^\circ

Explanation:

A right triangle is formed, in which the vertical elevation is the opposite cathetus and the horizontal distance is the adjacent cathetus, since we know these two values, we can calculate the angle of inclination using the definition of tangent:

tan\theta=\frac{opp}{adj}\\\theta=arctan(\frac{opp}{adj})\\\theta=arctan(\frac{28.1m}{100m})\\\theta=15.70^\circ

The critical angle for a liquid in air is 520, What is the liquid's index of refraction? 0.62 0.79 1.27 1.50
sammy [17]

Answer:

Liquid's index of refraction, n₁ = 1.27

Explanation:

It is given that,

The critical angle for a liquid in air is, \theta_c=52^o

We have to find the refractive index of the liquid. Critical angle of a liquid is defined as the angle of incidence in denser medium for which the angle of refraction is 90°.

Using Snell's law as :

n_1sin\theta_c=n_2sin\theta_2

Here, \theta_2=90

sin\theta_c=\dfrac{n_2}{n_1}

Where

n₂ = Refractive index of air = 1

n₁ = refractive index of liquid

So,

n_1=\dfrac{n_2}{sin\theta_c}

n_1=\dfrac{1}{sin(52)}

n₁ = 1.269

or n₁ = 1.27

Hence, the refractive index of liquid is 1.27
