A researcher is investigating the properties of two media. She doesn't know the indices of refraction of either media, n or nz, but performs the following experiments. First, she shines a light ray through material 1 at an angle of 0 = 30.4 deg with respect to the normal of the media interface. She measures an angle of refraction of 02 = 24.5 deg. N1 n2 01 02 In the second experiment she shines a light ray through material 2. What is the critical angle of the second material, i.e. at what point will the light no longer penetrate material 1? n1 N2
