It occurs when you did not fully close the air-hole on lighting up your Bunsen burner. Flames are observed to be green and it also produces a soot. Therefore we should immediately turn off the gas supply as the unburnt gas would fill the air, making the room flammable.
what causes the burner to strike back and what must one do when this happens?
A strike back will occur whenthe air hole of a Bunsen burner was not closed when lighting the Bunsen burner. You will then see a flame in the air hole of the Bunsen burner and may hear a strange noise . If a strike back happens, you should turn off the gas tap and inform the teacher immediately. Do not touch the chimney of the Bunsen burner as it is extremely hot. You can light the Bunsen burner again when the chimney has cooled down. :)

Striking back of a burner means that the burner's air hole is not open all the way. This causes an air shortage that needs to reach the gas. This results in too much air buildup through it, which causes the flame to burst out of the air hole.
Sodium(Na)?
If there is not a sufficient supply of oxygen, the flame will be smoky from excess of carbon.
The heat of the flame gives off energy to the ions. This results in electrons jumping out of their ground state and into their excited state. From a lower subatomic level to a higher one. When the electrons fall back down, the give off a color.

Project Strike Back was created in 2001.
Flame luminosity occurs because of lack of oxygen. Also, the air holes in the Bunsen burner affects the flame.

The Wildhearts Strike Back was created in 2004-10.
shear
The stress that causes strike-slip faults is produced by a shearing force and so is called shear stress.
