Narrative:

I was departing runway 10R with the intention of turning north after departure. An airliner had just departed runway 10L. The tower advised me to turn the crosswind; as soon as practicable but as a student pilot at the time I did not fully understand what that meant. As I climbed straight ahead; my instructor sitting in the right seat said nothing. At about 400 feet; I began to make the left turn. About 5 seconds after I completed the left turn; the airplane shook violently with what seemed to be a rapid-fire vibration. It seemed we were flying through 1000 tennis balls. We heard and felt the rapid-fire vibration. I asked my instructor what that was and he stated that the controller advised us to turn as soon as possible. He stated that was wake turbulence.I believe that if the controller stated; 'make the left turn at 200 feet' (for example) it would have been more clear to me as a student pilot; what to do.
