Question

2. What value did you calculate for the index of refraction of the acrylic block in Part 2? How does your value compare to the accepted value of 1.50? Calculate the percentage error. Different materials have distinct indexes of refraction. Explain how you might identify a material based on experiments like this one. Mention at least one of the difficulties in identifying materials based on their indexes of refraction.

Answer 1

"What value did you calculate for the index of refraction of the acrylic block in Part 2?"

Did you try the calculations in this activity? What did you get?

Answer 2

I tried to do it but i didnt understand the experiemnt

Answer 3

Sorry, I can't be of much help here. To answer this question you have to be able to get to the point where you calculate the value of the index of refraction.

Answer 4

Well i did get a value of 2.31 when id did it could i use that?

Answer 5

This value of n seems much too high for acrylic. Check your calculations.

Answer 6

its suppose to be closer to 1.50? that's what i though but let me check my work

Answer 7

I looked it over and I think that 1.64 is it @ghuczek

Answer 20

can you help?

Answer 21

yea

Answer 22

yay great thanks so much lets get started xD lol

Answer 23

XD

Answer 24

so whats first?

Answer 25

okay and your answer yyyou have is right

Answer 26

how do i ccalcualte the percentage error?

Answer 27

mhm

Answer 28

??

Answer 29

You calculate it with the following equation:

\[ percent \space error = {|actual-theoretical| \over theoretical} \times 100\]

Answer 30

Where "actual" is your measured value and "theoretical" is the value you expect it to be. The vertical lines in the equation mean you need to find the absolute value of the difference, so just take the positive of whatever number you get.

And @bohotness...you ok? :P

Answer 31

yes

Answer 32

hy

Answer 33

I got it thank you
