3. The wave properties of electrons have been observed, but there are no observable wave properties of baseballs. Below are data that represent electrons and baseballs in motion. electron baseball Mass (kg) 9.11 x 10 1.00 x 10 Speed (m/s) 3.00 x 10 36.3 (a) Using the data to support your answer, explain why wave properties of electrons have been observed. (Calculations alone will not yield full marks.) (2 marks) (b) Using the data to support your answer, explain why wave properties of baseballs have not been observed. (Calculations alone will not yield full marks.) (2 marks)
