Biz jets need to be careful of them at altitude when passing close to the cruise path of a heavy. Can wreak havoc on the smaller jet. Search for the Challenger Jet damage occurred after they hit the vortices from an Airbus A380 in the Middle East.
Here is another good video. Lots of them out there explaining this.

According to Flight Service Bureau, the international flight-planning organization, the Challenger encountered severe wake turbulence at about noon local time on January 7 while cruising at FL340 as the A380 passed 1,000 feet above it and slightly off track. One to two minutes later, the business jet rolled uncontrollably at least three times, causing serious injuries to some of the nine people on board.
This is why I was nervous following a DC10 into Cedar Rapids when I was in a C152 on my fist solo cross country in the post pages ago. Land after, as in further down the runway, the larger aircraft. Be in the air at a point before the other aircraft took off, even with the time delay. They do not dissipate well.
