HELP!!!!
Will and Grey got new RC cars for Christmas. They wanted to race the cars in the front yard. After charging the batteries, they tried to race but the cars wouldn't work. Using your knowledge of waves, what would be the best solution to the interference they are experiencing?
Take the cars back to the store, they are clearly broken.
Change the batteries, they didn't charge all the way.
Change the frequency of the one of the cars to a different one.
There is no good solution.
