Q1. Wave-particle Duality and Heisenberg Uncertainty
Principle (Easy)
Consider a spaceship weighing 5 tons
A) What is the wavelength associated with it if it is
flying 2 times the speed of light? h= 6.626 x 10-34 J.sec; c= 3
x108 m/sec
B) If the speed of the spaceship is known with a precision
of 5%. What is the uncertainty in its position?
