Refraction and reflection both shows the wave property of light and the difference between them is that during reflection the medium of light will not change while in refraction the light will change its medium

so in reflection of light we use that angle of incidence = angle of reflections with respect to normal

While in refraction we use Snell's law

n_1sin\theta_1 = n_2 sin\theta_2

Diffraction of light is the phenomenon of light in which light will bend at the corners and enter into the region of dark

While absorption is the phenomenon of energy absorption when light incident on any medium or surface

Avery is experimenting with a simple circuit. She measures the current in the circuit three different time
sammy [17]

The current in each experiment increases with increase in the voltage. Similarly, the association between resistance and the current in a circuit shows that increase in the resistance shows a reduction in the current, vice versa.

Ohm's Law states that the voltage across an electric conductor is directly proportional to the current(I) passing through it provided the resistant is constant.

So;

V ∝ I

V = IR  

where

  • R = constant

The objective of this question want us to determine: How did the current change for each test provided that Avery uses a 1.5-volt battery, then she uses a 3-volt battery and lastly she uses a 9-volt battery, given that the resistance is constant through out the whole process.

In the first experiment;

  • 1.5 = IR

In the second experiment;

  • 3 = IR

In the third experiment;

  • 9 = IR

Therefore, we can conclude that the current in each experiment increases with increase in the voltage. Similarly, the association between resistance and the current in a circuit shows that increase in the resistance shows a reduction in the current, vice versa.
