Question 4

In an immersion lithography system, an ultraviolet laser beam transitions from air into an experimental liquid. The wavelength of the ultraviolet light in the liquid is observed to be exactly 58\displaystyle \frac{5}{8}85​ of its wavelength in air.

What is the refractive index of this liquid?

A

0.630.630.63

B

1.261.261.26

C

1.601.601.60

D

2.562.562.56
