Hej Lanedance, thanks for taking the time. The slit length is never specified so the slit formula cannot be applied to get the wave length. I made and attached a simple sketch of the problems setup, but I guess since the difference in overall path length between the two paths doesn't...

1. With the later on given info, is it possible to through geometry calculate the wave length of a HeNe Laser? 2. Homework Equations and facts A Helium Neon laser emitts light through a double slit and towards a screen where a central image and the first dimmer bands can be seen. The...

Thanks for the time LowlyPion, feedback much appreciated. Pete

Hi, thanks for the reply. There is no info on how the centre of mass is moved compared to the seat of the swing. Nor is there any info on how the persons weight is divided. But if I am not mistaken the centre of mass in a human is located in the very low stomach. Assuming this is correct, the...

Homework Statement A swing in a playground is set in motion without anyone on it. Thereafter a person sits on it, as close to static as possible while the swing is in motion. Finally a person is standing on the swing, the swing in motion. Homework Equations Under ideal circumstances...
