What value relates the speed of light in a vacuum to the speed of light in a given material? A) angle of incidence B) angle of refraction C) index of refraction D) index of reflection

C) Index of refraction

Explanation:

Index of refraction also known as refractive index is defined as speed of light in a vacuum divided by the speed of light in a given material.

The formula for Index of refraction is:

n = c ÷ v

where n represents Index of refraction,

c represents speed of light in a vacuum,

v represents speed of light in a given material.

The speed and direction of light changes when it moves from one medium to another. The change in direction is basically called refraction.

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2
