Answer 2

well you are given the equation

n1 Sin A1 = n2 Sin A2

you are also given the values of n1, A1, and A2

you just need to plug them into the equation

(1)sin(60) = n2*sin(26.8)

and solve for n2

Answer 3

yup

Answer 4

just to double check, it just says "60" and "26.81" right, it doesn't have any degree symbol
° right? ;;

Answer 5

actually yes both of them do. Does that make a difference?

Answer 6

yes, units are very important, you will need to change your calculator to degree mode

so using degrees we get 1.92076 not -0.30

Answer 7

I don't believe my calculator has a degree mode. Is there any online calculator that I could use?
