What is the speed of light in case of Critical Angle?
When light travels from an optically denser to a rarer medium, it bends away from the normal and at a specific angle of incidence, the angle of refraction is ${90}^{\circ}$. When the angle of ...

How can the speed of light at the interface separating two media be equal to that of one of the media?
When light passes from an optically denser medium to an optically rarer medium, it bends away from the normal in accordance with the Snell's Law of refraction $\mu_1\sin i =\mu_2\sin r$ where $\mu_1$ ...

Are images formed due to reflection or refraction and what do we see? HOW?
I am getting extremely confused about what we see as individuals : do we see reflected rays or refracted rays and what does our brain interpret?
The concept has bewildered me for a long time. Googling ...

Proving that angle of incidence over angle of reflection is constant in Snell's Law
First let me state what I think I know: Snell's Law states that $\frac{sin(i)}{sin(r)} = \frac{v_1}{v_2}= \frac{\lambda_1}{\lambda_2}= \frac{n_2}{n_1}$ where i is the angle of incidense and r is the ...

What happens when light is reflected from a surface moving in a medium with a huge refractive index?
Imagine a mirror is moving away from a light source in a substance through which the speed of light is very slow -- so slow that the speed of the mirror is close to being the same as the speed of the ...
