La siguiente imagen muestra el recorrido que hace Gustavo para llegar desde su casa(punto A) hasta la casa de su amigo (punto F). Las medidas están en metros. a) Si Gustavo sigue el camino indicado en la imagen (f-g-h-i-j), ¿Cuántos metros recorre hasta la casa de su amigo? b) ¿Cuántos metros se desplazó Gustavo? (Use teorema de Pitágoras) *

where is the photo and the answer choices?

speed of light in vacuum is 300,000 km/s

speed of light in other mediums is given by the expression v = c/n, where c is the speed of light in vacuum and n is the refractive index of medium.

for the first medium v = 200,000 km/s

  so, refractive index of medium = 300000/200000 = 1.5

    1.5 refractive index is usually for glass. so first medium is glass.

for the second medium v = 250,00 km/s

so, refractive index of medium = 300000/250000 = 1.2

    1.2 refractive index is usually for water. so second medium is water.

for the third medium v = 0 km/s

so, refractive index of medium = 300000/0 = ∞

    ∞ refractive index is usually for opaque mediums. so third medium is opaque medium.

there are no components of a physical goal mentioned on the list of choices that you've provided.
