Question
When light travels from a denser medium to a rarer medium, what happens to its speed?Question 5Select one:a.It becomes zero.b.It decreases.c.It increases.d.It remains the same
Solution
When light travels from a denser medium to a rarer medium, its speed changes. To determine how the speed changes, we need to understand the concept of refractive index. The refractive index is a measure of how much a medium can slow down the speed of light compared to its speed in a vacuum.
In general, when light passes from a denser medium to a rarer medium, the refractive index of the rarer medium is lower than that of the denser medium. This means that the rarer medium has less ability to slow down the speed of light. As a result, the speed of light increases when it travels from a denser medium to a rarer medium.
Therefore, the correct answer to the question is: c. It increases.
