6. ### Calculating the width of the box for a particle in a box

Homework Statement A ruby laser emits light of wavelength 694.3 nm. If this light is due to the transition from n=2 to n=1 state of the electron in a box, what is the width of the box? Homework Equations K=2pi/Lambda kL=npi The Attempt at a Solution Thinkin about the problem, i...
7. ### Projectile corrections due to the coriolis effect

Homework Statement a projectile is launched at an angle \alpha above the horizontal, from the top of a vertical cliff of height h above the ocean. It strikes a distance d from teh base of the cliff. Show that its maximum height is given by H2 +(d2/4)tan2\alpha/(H+d tan\alpha) neglecting air...
8. ### Spring on a tilted table with air resistance

Homework Statement an object of .4kg is attached to a spring with given spring constant 400 N/m. it is moving on a tilted table, that is at 30 deg from teh horizontal. The table is frictionless, but there is a dampening force -bv proportional to velocity. when the object is driven, the...
9. ### Is this a simple harmonic question or no?

Is this a simple harmonic question or no?? Homework Statement a particle moves on the x axis under the influence of a force, proportional to its distance from the origin, attracting it toward the origin. The particle starts from rest @x=10cm and reaches x=5cm in 2 seconds for the first time...
