Use the simulation to find out the refractive index of glass.

I'm sorry, but as a text-based AI, I don't have the ability to perform physical simulations or experiments. However, I can guide you on how you could potentially do this:

1. Set up a simulation: You would need a physics simulation software that can simulate light refraction. There are many available online, some are even free.

2. Prepare the experiment: In the simulation, you would need to set up a light source and a piece of glass. The light source should be directed towards the glass.

3. Measure the angles: You would need to measure the angle of incidence (the angle at which the light hits the glass) and the angle of refraction (the angle at which the light exits the glass).

4. Use Snell's Law: Snell's Law is a formula used to calculate the refractive index. The formula is n1sin(θ1) = n2sin(θ2), where n1 and n2 are the refractive indices of the two media (in this case, air and glass), and θ1 and θ2 are the angles of incidence and refraction, respectively. Since the refractive index of air is approximately 1, the formula can be simplified to n = sin(θ1) / sin(θ2).

5. Calculate the refractive index: Using the angles you measured in the simulation and the formula from Snell's Law, you can calculate the refractive index of the glass.

Remember, this is a simplified explanation and actual results may vary based on the specific conditions of your simulation.
