Ede4ka [16]

Explanation:

Types of light microscope

1. Compound , and 2. Stereo Microscope

Compound microscope has two lens system also called compound lens system. The objective lens and the eyepiece lens. The magnification provided by the objective lens is compounded by the eyepiece lens, the a higher magnification is observed.

The index of refraction for a certain type of glass is 1.641 for blue light and 1.603 for red light. When a beam of white light

exis [7]

Answer:

The angle between the emergent blue and red light is $0.566^{o}$

Explanation:

We have according to Snell's law

$n_{1}sin(\theta _{i})=n_{2}sin(\theta _{r})$

Since medium from which light enter's is air thus $n_{1}=1$

Thus for blue incident light we have

$1\times sin(40.05)=1.641\times sin(\theta _{rb})\\\\\therefore \theta _{rb}=sin^{-1}(\frac{sin(40.05)}{1.64})\\\\\theta _{rb}=23.10$

Similarly using the same procedure for red light we have

$1\times sin(40.05)=1.603\times sin(\theta _{rr})\\\\\therefore \theta _{rr}=sin^{-1}(\frac{sin(40.05)}{1.603})\\\\\theta _{rr}=23.66^{o}$

Thus the absolute value of angle between the refracted blue and red light is

$|23.66-23.10|=0.566^{o}$
