Question

Roberto was testing how light interacted with a material he had just developed. The initial speed of light was 3.0 × 108 m/s. The final speed of light after it changed direction was 1.7 × 108 m/s. What type of interaction took place?

Answer 1

The answer to the question would be Refraction.

as we know the two possible answers are refraction and reflection. The questions shows a decrease in speed thus being refraction as a ray in a reflection would not lose its speed. Hope this helps!

Answer 2

Analyzing the question, we can classify the effect of refraction as the speed is reduced when entering the middle.

What is the concept of refraction?

Refraction of light is a phenomenon that occurs in electromagnetic waves that are transmitted through some translucent or transparent medium. When light penetrates refractive media, that is, those capable of refracting light, its speed decreases.

the type of interaction that happend is refraction as the speed is reduced when entering the middle.
