Question

the changing of light speed due to
a:change of medium
b:density of medium
c:refracticve index of medium
d:all of the above​

Answer 1

Answer:

d

Explanation:

I think the answer is opesion D all of the above

Answer 2

Answer:

d.) all of the above

Explanation:

1.)change in medium can change the density, refractive index and can cause retraction

2.) density - if medium is denser the ray moves towards the normal ray

And if the medium is less denser or lighter so the ray moves away from normal ray

3.) refractive index, this again relates to density and speed of light
