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?

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!

its refraction just did the question on edge

wavelength variability is the right one

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..
