Light of wavelength 550 nm illuminates a double slit, and the interference pattern is observed on a screen.
1. At the position of the m =2 maximum (bright fringe), how much farther is it to the more distant slit than to the nearer slit?
2. At the position of the m= 2 minimum (dark fringe), how much farther is it to the more distant slit than to the nearer slit?

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
