Problem 42

(a) Calculate the momentum of a photon having a wavelength of 2.50 m . (b) Find the velocity of an electron having the same momentum. (c) What is the kinetic energy of the electron, and how does it compare with that of the photon?

Step-by-Step Solution:
Step 1 of 3

Momentum! Reminder: If two objects move at a constant velocity for the same amount of time, the distance they travel is proportional to their velocity. Δx vt = Δx v = t Both carts start at the same velocity and travel the same distance in the start in the middle of the track.th hit the barriers at the same time if they If I add weight to cart #2, enough to double its mass, then: 1. Cart #1 and Cart #2 still get to the ends at the same time. 2. Cart #2 arrives first. 3. Cart #1 arrives first. 4. Cart #1 moves but Cart #2 doesn’t move. Where should I put the carts to make sure that #1 and #2 arrive at the same time 2m =m1. 2 1. Cart #1 should travel half the distance of #2. 2. Cart #2 should travel half the distance of #1. 3. Cart #1 should travel one third the distance of #2. 4. Cart #2 should travel one third the distance of #1. Where should I put the carts to make sure that #1 and #2 arrive at the same time 3m =m1. 2 1. Cart #1 should travel half the distance of #2. 2. Cart #2 should travel half the distance of #1. 3. Cart #1 should travel one third the distance of #2. 4. Cart #2 should travel one third the distance of #1. What happens if cart #1 discharges without touching cart #2 1. It still travels to the end of the track. 2. It travels in the o
