Explanation in Layman Terms:

Since we have mentioned earlier of how Vix is an indicator of annual market volatility over the next 30 days, lets have a easier way of explaining VIX. For example consider India VIX to be at 20. This means there is an expected annual change of 20% in the nifty over the next 30 days. So we can consider the value of Nifty to trade in a range between +20% and -20% from the current price for the next 1 year for the next 30 days. So if nifty is trading at 18000 then for the next 1 year nifty is expected to trade between 14400(-20% of 18000) and 21600(+20% of 18000).

If you want to know the short term vix, say for example for a 1 month time period, you can use the formula Vix/(√(T)) where T is the time period. Since we are calculating for 1 month and there are 12 months in a year we use Vix/(√(12)) which is 20/3.464 = 5.78%. So the market volatility that can be expected for next one month is 5.78% from 18000. Which is 16959.6(-5.78%) to 19040(+5.78%).
