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}

Acceleration is defined as the change in velocity divided by
denpristay [2]

Answer:

Time elapsed

Explanation:

Acceleration is a vector quantity. It is defined as:

a=\frac{v-u}{t}

where

v is the final velocity

u is the initial velocity

t is the time elapsed

Acceleration is measured in meters per second squared (m/s^2). It must be noticed that acceleration is a vector, so it also has a direction. In particular:

- when acceleration is negative, it means that the object is slowing down, so acceleration is in opposite direction to the velocity

- when acceleration is positive, it means that the object is speeding up, so acceleration is in the same direction as the velocity
