Answer:
a. Interference patterns are observed when a wave passes through a barrier with two slits
Explanation:
Interference is a situation where two waves superimpose to form a new wave of a different amplitude. This amplitude can be greater, same or lower.
the diagram attached below shows the movement of a wave through a barrier with two slits.
you can notice the portions of the wave that overlap. This overlapping of waves is the interference.
Thus, option A is correct.
The other options however, are not correct. as shown below:
Option B is wrong as waves exhibit diffraction <em>(it is diffraction of the light wave that produces the rainbows we see in the sky)</em>
Option C is wrong as waves do not travel straight through slits always.
Option D is wrong as waves can also interfere constructively and destructively.
Answer:
0.895V
Explanation:
The emf of an electrochemical cell is obtained from the Nernst equation as shown in the images attached. The emf of an electrochemical cell is read from voltmeter in the circuit. The Nernst equation is used to obtain the emf of cell when it is not operated under standard conditions. That is the concentration of solutions is not 1M, temperature is not 25oc and pressure (for gases is not 1ATM)
