Although we have discussed single-slit diffraction only for a slit, a similar result holds when light bends around a straight, thin object, such as a strand of hair which ranges between 170-10 microns. in that case, a is the width of the hair strand. from actual laboratory measurements on a human hair, it was found that when a beam of light of wavelength 523.3 nm was shone on a single strand of hair, and the diffracted light was viewed on a screen 2.55 m away, the strand of hair was 1.50x10-5 m in thickness. what was the spacing between the first dark fringe on either side of the bright spot?

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.

the answer you are looking for is d. there are no holes for blood to enter or leave the system. your welcome

c) a core temperature of only ten thousand kelvin
