=2. In the lab frame shown below, stick L is at rest and stick M is moving left at speed v. According Marvin, the little man who lives on stick M, the length of stick L is Two meter sticks, labeled L (for lab) and M (for moving) are flying by each other at very high relative speed v. The gamma factor is =2. In the lab frame shown below, stick L is at rest and stick M is moving left at speed v. According Marvin, the little man who lives on stick M, the length of stick L is
Pink: 1m Yellow: 1/2 m Green: 2 m
Purple: None of these.
Answer: Yellow: 1/2m. According to Marvin, he(Marvin) is at rest and stick L is moving. "Moving sticks are shorter". So, according to Marvin, stick L is shorter by a factor of gamma=2.
