Answer the following questions to the best of your ability. Each response should be no longer than a paragraph.
Describe, the relationship between a material’s index of refraction, the speed of light in that material, and wavelength
Why do certain materials like water and glass have such close values of n, despite one being a solid and on being a
Why do diamond and glass have very different values of n, despite superficially looking similar?
The figure below shows a small light source with two rays from the light hitting the top surface
of a solid piece of plastic. The path that the light ray on the left follows as it goes through the
plastic is also shown.
Draw, specifically and precisely, the path the ray on the right follows through the plastic.
Explain, based on your findings from previous investigations, how you determined where to
draw the path in the plastic for the second ray.
Test the law of reflection. Consider the experiment shown in (Figure 1). Suppose you use a ruler in place of the x-axis. The ruler is parallel to the mirror and placed at a distance of 20 cm from the mirror. You installed a laser at x1 = 2.0cm. Also, you measured θ = 57 ∘. What should be the value of x2 in this experiment if the laser beam obeys the law of reflection? Neglect the experimental uncertainty. -->***Please use clear steps to explain. I am asking to understand. Not just seeking answers.*** <--
