Match the following steps in the scientific method to their definitions.
1. research the problem
use reliable sources, talk to experts, and take notes
2. organize data
create charts or graphs to display the results
3. design an experiment
come up with a question that can be answered
4. hypothesis
set up a procedure for testing your ideas; include variables and controls
5. choose a problem
must be testable and falsifiable

hèllo, sorry i really need some more points so if you need this qustion answered than retype it

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.
