Answer:
B. High optical density, and light travels more slowly through it.
Step-by-step explanation:
Refractive index is the property of a material that describes the change in the initial path of light and the rate at which light travels through it. And optical density of a material describes its absorption ability to rays or beam of light passing through it.
As the index of refraction of a material increases, therefore its optical density would increase. This would cause light to travel through it slowly. Unless the light has a high frequency.
A material with a high index of refraction has a high optical density, and light travels more slowly through it.
Answer:
4 cm
Step-by-step explanation:
Take the 11 cm on the bottom and subtract the 7 cm right above it.
Imagine the bottom half of this shape as a rectangle, the bottom and top side are of the same length. The top side would have to be 11 cm in length as well, so just subtract 11-7 to get the missing part.
