Based on what we know, we can confirm that the wave behavior being observed when light passes through media of different densities is refraction.
<h3>What is refraction?</h3>
This is a term used to explain the behavior of light as it moves through distinct mediums. This behavior includes a change in direction of the light due to its change in speed.
Therefore, the wave behavior being observed when light passes through media of different densities is refraction.

The kinetic energy of the ejected electrons will be 2782.5 ×10⁻²² eV.
<h3>What is threshold frequency?</h3>
The threshold frequency of incoming radiation is the lowest frequency at which photoelectric emission or electron emission is impossible.
The threshold frequency is the light frequency that causes an electron to dislodge and emit from the metal's surface.
From the photoelectric effect, the equation obtained as;
Hence,the kinetic energy of the ejected electrons will be 2782.5 ×10⁻²² eV.

To calculate the speed of the water leaving we use the formula,
Here h is the height of the water above the hole and g is the acceleration due to gravity.
Given,
Substituting the given value in above formula we get
Thus, water flow from a hole at the speed is 10.7 m/s
Answer: The answer would be C. When Octopus eject the water out, the water acts with an equal force on the octopus in opposite direction.
Explanation:
An octopus propels itself forward in the water by ejecting water backward through a funnel in its body.
Hope this helps! :D
