Any deviation in the image of an object when light passing from one medium to other is assciated to the phenomenon of refraction.

<h3>What is refraction ?</h3>

It is the deflection from a straight path undergone by a light ray while passing from one medium (such as air) into another (such as glass) in which its velocity is different.


Basically, the light refraction gives the pencil a slight magnifying effect, which makes the angle appear bigger than it actually is, causing the pencil to look crooked.

<h3 />
  • After Looking at the pencil from the side of a clear glass or resealable plastic bag filled three-fourths with water, we will see the light bends around the pencil, causing it to look bent in the water.

  • When the pencil tilt from side to side, It looks so dramatically broken on looking at it from different angles.
    We can magically “fix” the broken pencil by changing where the pencil is positioned in the glass.

Why does a candle relight if a match is held above the wick just after the flame is<br> blown out?
shutvik [7]

Answer with Explanation:

A candle relights when a match is held above the wick because its trail of smoke still contains some of the wax. When candles are burned, the heat of the flame turns the the wax (which is originally solid) into liquid (commonly near the wick) and then evaporates as gas. The vaporized wax actually protect the wick and this is the reason why it is not burned. So, when you put off a candle, the vaporized wax is still present near the wick. This, remember, holds heat and light energy. Thus, this explains why the candle can be relighted once you hold a match above the wick. It then allows the match to ignite.

Thus, this explains the answer.

What is the ground state electron configuration for B3+ ?
Arisa [49]

The ground state electron configuration is the arrangement of electrons around the nucleus of an atom with lower energy levels. The electrons occupying the orbitals of varying energy levels naturally falls towards the lowest energy state or ground state.
