Which type of circuit would be best to use for lights used for decorations? Question 1 options:

Parallel circuit. One bulb could go out and the strand will stay on.

Series circuit. One bulb could go out and the rest go out.

Parallel circuit. One bulb goes out and the rest go out.

Series circuit. One bulb could go out and the strand will stay on.

A parallel circuit is a better choice, because the strand will still work even if one bulb burns out.

speed of light in vacuum is 300,000 km/s

speed of light in other mediums is given by the expression v = c/n, where c is the speed of light in vacuum and n is the refractive index of medium.

for the first medium v = 200,000 km/s

  so, refractive index of medium = 300000/200000 = 1.5

    1.5 refractive index is usually for glass. so first medium is glass.

for the second medium v = 250,00 km/s

so, refractive index of medium = 300000/250000 = 1.2

    1.2 refractive index is usually for water. so second medium is water.

for the third medium v = 0 km/s

so, refractive index of medium = 300000/0 = ∞

    ∞ refractive index is usually for opaque mediums. so third medium is opaque medium.
