With the laser, the diffracted images on the wall and the light source were on opposite sides of the grating. however, for the hydrogen and sodium lights, the light sources and the diffracted images were on the same side of the grating. do you see any contradiction?

Acar of mass m goes around a banked curve of radius r with speed v. if the road is frictionless due to ice, the car can still negotiate the curve if the horizontal component of the normal force on the car from the road is equal in magnitude to 101) a) mv2/r b) mg/2. d) mg e) tan[v2/(eg)]
