Which of the following experiments or phenomena provided evidence for the particle nature of light?
interference patterns observed during the double slit experiment.
expulsion of electrons with varying frequencies of light observed in the photoelectron effect.
polarization of light
the observed bending of light thought a prism and resulting spectrum.

Expulsion of electrons with varying frequencies of light observed in the photoelectron effect.

this a false

explanation:

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.
