B. it showed that the wave nature of light is a probability statement of where photons are going to be
Explanation:
When the light propagates through a medium it is taken to act as a wave, it shows all the features of a wave such as reflection, refraction, diffraction.
But when the light ray is incident on a surface generating an energy interaction with the particles of the matter on which it is incident then it is treated as matter. Light is made of particles called photons.
The collision of photons with the surface electrons in some materials leads to the ejection of the valance electrons from the surface in excited state.
In absence of friction, total mechanical energy must be conserved.
This means that the change in gravitational potential energy (in magnitude) must be equal to the change in kinetic energy:
As it can be seen, the mass m is on the both sides of the equation, which means that it can be simplified.
We can solve this equation for v (speed at the bottom) as follows:
As it can be seen, the mass has no part in the equation, so, due both are starting from the same height, both people have the same speed at the bottom.
