A ray of light hits the surface between air and an unknown material at an angle A of 41.1°. It travels through the unknown material at an angle B of 27.7° relative to the vertical. What is the index of refraction of the material?

Refractive index of second material will be 1.41

Explanation:

It is given refractive index of first material, that is air

Angle of incidence = 41.1°

Angle of refraction from second material = 27.7°

We have to find the refractive index of second material.

Now from Snell's law

So refractive index of second material will be equal to 1.4

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.
