Answer:
The ratio of the speed of light in a vacuum to the speed of light in the material it is passing through
Explanation:
- Index of refraction also called refractive index is the ratio of the sine of angle of incidence to the sine of angle of refraction, this is according to the Snell's Law.
- <u>The value of index of refraction</u> may be calculated from the ratio of the speed of light in vacuum to the speed of light in a second medium of a greater density.
- Therefore,<em><u> refractive index refers to the speed of light in a vacuum divided by the speed of light in the medium.</u></em>
30° South, 60° east I'd say.
Answer:
Explanation:
Net force is determined by adding up all of the individual forces on an object. For example, to determine the net force on an airplane, you would add up the lift, weight, thrust, and drag. If forces are in opposite directions, like lift and weight, then you subtract them
