Uh ... simple trig. ##\theta_1 = \theta_2 + \gamma##

Aah thank @phinds! Brain must have been dead, I see that now :)

1. What is light passing through a slab?

Light passing through a slab refers to the phenomenon of light traveling through a medium that has a certain thickness or depth, known as a slab. This can occur in various materials such as glass, water, or even air.

2. How does light behave when passing through a slab?

When light passes through a slab, it can either be transmitted, absorbed, or reflected. The behavior of light depends on the properties of the slab, such as its thickness, density, and refractive index.

3. What is the difference between transparent and opaque slabs when it comes to light passing through?

A transparent slab allows light to pass through it without any significant change in direction or intensity. On the other hand, an opaque slab does not allow light to pass through at all, as it either absorbs or reflects all of the light that hits it.

4. How does the angle of incidence affect light passing through a slab?

The angle of incidence, which is the angle at which light hits the slab, plays a crucial role in determining how light behaves when passing through a slab. The angle of refraction, or the angle at which light exits the slab, is dependent on the angle of incidence and the refractive index of the slab.

5. Can light passing through a slab be used for practical applications?

Yes, light passing through a slab has many practical applications in various fields such as optics, telecommunications, and imaging. For example, lenses and prisms are made of slabs of glass that manipulate light to form images, and fiber optic cables use slabs of glass to transmit information through light signals.
