Lisa sees the image below as she researches the behavior of light.
which behavior is the spoon in the top image most likely being used to illustrate?
a refraction
b absorption
c reflection
d bounce

The answer to the question is Refraction.

EXPLANATION:

The spoon half dipped inside the water is appeared to be bent. This is due to the optical  phenomenon called refraction.

Refraction is the property of light by virtue of which light ray bends away or towards the normal at the point of incidence when it incidents obliquely at the refracting surface.

In the given figure, light rays are coming from air which is optically rarer medium as compared to water. So, the ray, after striking the air-water interface, gets bent towards the normal in the optically denser medium i.e water.  It is so because the velocity of light in optically denser medium is less as compared to rarer medium.

We view the object due to the light. As light rays are bent, so the spoon is appeared to be bent.

an ion is a charged atom or molecule. it is charged because the number of electrons do not equal the number of protons in the atom or molecule. an atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
