A layer of oil (n = 1.38) floats on an unknown liquid. A ray of light originates in the oil and passes into the unknown liquid.
Vinil7 [7]

Answer:

Refractive index of unknown liquid = 1.56

Explanation:

Using Snell's law as:

n_i\times {sin\theta_i}={n_r}\times{sin\theta_r}

Where,  

{\theta_i}  is the angle of incidence  ( 65.0° )

{\theta_r} is the angle of refraction  ( 53.0° )

{n_r} is the refractive index of the refraction medium  (unknown liquid, n=?)

{n_i} is the refractive index of the incidence medium (oil, n=1.38)

Hence,  

1.38\times {sin65.0^0}={n_r}\times{sin53.0^0}

Solving for {n_r},

Refractive index of unknown liquid = 1.56

What is true about semiconductors?
Iteru [2.4K]

In semiconductors, you can change how easily electrons move through them. That is option 2.

<h3>What are semiconductors?</h3><h3 />

Semiconductors is defined as those substances that possess the characteristics of both metal and non metal.

Examples of semiconductors include the silicon, germanium, and gallium arsenide elements.

The semiconductors are able to conduct electricity through the presence of electrons and holes in them.

The movement of these electrons can be controlled through the addition of impurities to the semiconductor material.

Therefore, in semiconductors, you can change how easily electrons move through them.
