QUESTION:

Problem 9CQ

Suppose light were incident from air onto a material that had a negative index of refraction, say –1.3; where does the refracted light ray go?

ANSWER:

Solution 9CQ

Step 1 of 4

Refraction or Snell’s law can be written as,

n1 sin θ1 = n2 sin θ2

Here, the indices of refraction of two different media in which light ray travels is n1 and n2 and the angle of incidence and angle of refraction is θ1 and θ2.
