Data:
refractive index of air=1.00
speed of light in a vacuum=3.00×108m/s
In an experiment shining light through air into transparent wafflecheese, 𝑖=60∘ and 𝑟=16∘.
Calculate the speed of light in wafflecheese.

Hi, welcome to TSR.

As you are new, you may not know that students or users are expected to show their working or line of thoughts for others to guide or help you.

For this question, it is an application of “law of refraction” or Snell’s law and knowledge of refractive index as the ratio of the speed of light in different transparent medium.

Based on the following info,
refractive index of air = 1.00
𝑖=60° and
𝑟=16°.

you can find the refractive index of the transparent wafflecheese (have not seen such waffecheese before, it would be interesting to see one)

Then use the “definition” of refractive index of transparent wafflecheese as the ratio of speed of light in vacuum to transparent wafflecheese transparent wafflecheese to compute the speed of light in transparent wafflecheese.


Note that there are some implicit assumption where the refractive index of air is 1.00 and the speed of light in air is also 3.00×108 m/s.

That's really helpful, thank you.
